Explanation- on resolving forces into rectangular components in equilibrium forces (F1+1/ 2 )N are equal to 2 N  and F2 is equal to ( 2 + 1 / 2 )N

F1+1/ 2 = 2

F1= 2 - 1 / 2 = 2 - 1 2 = 1 2 = 0.707 N

F2= 2 + 1 2 = 2 + 1 2 = 3 2 = 2.121 N

Filling out the Decision Making Form during IISER counselling is crucial because it determines how your allotted seat is treated in future counselling rounds. Here's why it's important:

This is a assertion and reason answer type question as classified in NCERT Exemplar

At constant temperature, the pV vs V plot for real gases is not a straight line because there is intermolecular attraction present in real gases which is absent in ideal gases; hence ideal gases form a straight line in the pV vs V plot at constant temperature.

This is a Long Answer type Questions as classified in NCERT Exemplar

Explanation – horizontal velocity ux= vs

During projectile motion horizontal velocity remains unchanged

Vx=ux=vs

In vertical direction vy2= uy2+2gH

Vy= 2 g H

Resultant speed of the ball at the bottom

V= v x 2 + v y 2

V= v s 2 + 2 g H

b) when ball is given horizontal velocity and a small downward velocity

in horizontal direction V'x=ux=vs

in vertical direction vy'2= uy2+2gH

resultant velocity of the ball at the bottom

v'= v s 2 + u 2 + 2 g H

This is a Long Answer type Questions as classified in NCERT Exemplar

Explanation- displacement vector of particle is r (t)=? Acos w t + ? Bsinwt

X=Acoswt

x/A= coswt………1

displacement along y axis is

y=Bsinwt

y/B= sinwt……….2

squaring and then adding eqn1 and 2 we get

x2/A2+y2/B2=cos2wt+sin2wt =1

this is an equation of ellipse. Therefore trajectory of particle is an ellipse.

b)v= dr/dt= id/dt (Acoswt)+jd/dt (Bsinwt)

 ? [A (-sinwt)w]+? [B (coswt).w]

= -? Awsinwt+? Bwcoswt

Acceleration a= dv/dt

So a= -? Awd/dt (sinwt)+? Bw [-sinwt]w

=? Aw2coswt-? Bsinwt

= -w2r

So force acting on the particle f=ma=-mrw2

This is a Long Answer type Questions as classified in NCERT Exemplar

Explanation – centripetal force, F= mv2/r= f= μ N = μ m g

V= μ r g

For path ABC path length =3/4 (2 π 2 R )= 3 π R = 3 π 100 = 300 π

V1= μ 2 R g = 0.1 × 100 × 10 = 1.414 m / s

So t= 300 π 1.414 = 66.6 s

For path DEF  path length = 1 4 2 π R = 50 π

V2= μ R g = 0.1 × 100 × 10 = 10 m s

So t2= 50 π 10 = 15.7s

For path CD and FA

Path length =R+R= 200m

T= 200/50= 4s

Total time = 66.6+15.7+4= 86.3s

This is a Long Answer type Questions as classified in NCERT Exemplar

Explanation- as angle is 45

On smooth inclined plane acceleration will be a = gsin θ

So acceleration will become a= g/ 2

Using equation of motion s =ut +1/2at2

S= 1 2 g 2 T 2

On rough inclined plane a = g (sin θ - μ c o s θ )

= g (sin 45 - μ c o s 45 )= g ( 1 - μ ) 2

So s=ut +1/2at2

S= 0+ 1 2 g 1 - μ 2 ( p T ) 2

Comparing two above distance

12g1-μ2 (pT)2= 12g2T2

So after solving we get μ= (1-1/p2)
