When the ring rotates about its axis with a uniform frequency fHz, the current flowing in the ring is

I=q/T=qf

Magnetic field at the centre of the ring is

WBJEE application form number will be available after registration is completed. Once students can check their application number, they should keep it for safe since it will be needed for login and admission.

$\left|A-xI\right|=\left|\begin{array}{cc}\hfill 1/2-x\hfill & \hfill 1/2\hfill \\ \hfill a\hfill & \hfill b-x\hfill \end{array}\right|=x^2-\left(b+\frac{1}{2}\right)x+\frac{b-a}{2}$

from Cayley – Hamilton Theorem

$A^2-\left(b+\frac{1}{2}\right)A+\left(\frac{b-a}{2}\right)I=0$

$\Rightarrow A^3=\left({\left(b+\frac{1}{2}\right)}^2-\left(\frac{b-a}{2}\right)\right)A-\left(b+\frac{1}{2}\right)\left(\frac{b-a}{2}\right)I$

$\therefore {\left(b+\frac{1}{2}\right)}^2-\left(\frac{b-a}{2}\right)=1\&\left(b+\frac{1}{2}\right)\left(\frac{b-a}{2}\right)=0$

$\therefore \left(a,b\right)=\left(\frac{1}{2},\frac{1}{2}\right),\left(-\frac{3}{2},-\frac{3}{2}\right),\left(\frac{3}{2},-\frac{1}{2}\right)$

GATE paper code is engineering branch code. Candidates must check paper code carefully while filling application form. The details are available at GATE's official website- gate2026.iitg.ac.in.

A = {1, 2, 3, 4}. As (4, 4) $\notin$  R so not reflexive

Also not transitive

The following factors decide the COMEDK UGET cutoff:

• Number of applicants
• Availability of seats
• Exam difficulty level
• Category of the students 
• and several other deciding factors

Students should keep their 10^th and 12^th standard examination mark sheet ready before filling WBJEE application form. By having these documents ready, students will be able to correctly fill required information in application form.

While filling WBJEE application form, documents have to be uploaded. Students have to upload their passport size photograph in application form. Dimension of scanned photograph should be 3.5 cm x 4.5 cm and file size should be between 10 KB to 100 KB.

If the two lines are perpendicular then a = 2

D = 0       $\Rightarrow$    c = -3

(D = abc + 2fgh - af² – bg² - ch²)

The authority announces the COMEDK UGET cutoff separately for each round of counselling. Candidates will be able to check the COMEDK cutoff from the official website, comedk.org.

The GATE paper code for metallurgical engineering is MT. The eligible two-paper combination for metallurgical engineering is Engineering Sciences (XE). Candidates who want to opt for the MT paper must check the paper code carefully before applying. To apply for secondary paper, candidate must select from the drop-down menu available in the application form. 

$\frac{x}{4}=cost-sint...\left(1\right)$

$\frac{y}{5}=cost+sint$ . . . . (2)

(1)² + (2)² gives

${\left(\frac{x}{4}\right)}^2+{\left(\frac{y}{5}\right)}^2=2$

$xdy+ydx=\frac{xydx}{\sqrt[]{1-x^2}}$

$\frac{d\left(xy\right)}{xy}=\frac{dx}{\sqrt[]{1-x^2}}$

Integrate both sides we get

logexy = sin1 x + C

$y^2=x,a=\frac{1}{4}$

$x^2=-y,b=\frac{1}{4}$

$A=\frac{16\left|ab\right|}{3}=\frac{1}{3}$

InA-O-H, if EN of ' A' is 2.1 then it will be neutral, as X_A-X₀=X₀-X_H. (where X is EN)

Bond order in N $N_2$ and O $O_2^{2+}$ is 3 (calculated by energy level diagram)

Yes, candidates can change their GATE paper at the time of GATE form correction process. The last date to change primary paper is November 10. Candidates can edit at the GOAPS portal using their enrollment ID and password.
