Correct Option - 3

Detailed Solution:

$a = \frac{F}{m} = \frac{m v}{m} = \frac{1 * 10}{2} = 5 m / s e c^{2}$

A travelling microscope is used to determine the refractive index of a glass slab. If 40 divisions are there in 1cm on main scale and 50 Vernier scale divisions are equal to 49 main scale division, then least count of the travelling microscope is __________× 10^-6 m.

Vishal Baghel

Let ‘x’ be the value of one division on main scale

$x = \frac{1}{40} c m$

Let ‘y’ be the value of one division on vernier

Now given

50y = 49 x

$y = \frac{49 x}{50}$

$\begin{array}{l} = 5 \times 1 0^{- 4} c m \\ = 5 \times 1 0^{- 6} m \\ 5 \end{array}$

A ball of mass 0.5 kg is dropped from the height of 10m. The height, at which the magnitude of velocity becomes equal to the magnitude of acceleration due to gravity, is __________m.

[Use g = 10m/s²]

Payal Gupta

Let ‘h’ be the height at which velocity becomes equal to magnitude of Acceleration

v = g = 10

v = u + at

10 = 0 + 10t

t = 1 sec

$h = u t + \frac{1}{2} a t^{2}$

$= 0 \times 1 + \frac{1}{2} \times 10 \times 1 \times 1$

= 5m

In the arrangement shown in figure a₁, a₂, a₃ and a₄ are the accelerations of masses m₁, m₂, m₃ and m₄ respectively. Which of the following relation is true for this arrangement?

Vishal Baghel

$\sum_{}^{} \vec{T} . \vec{a} = 0$

$\frac{T}{2} a_{1} + \frac{T}{4} a_{2} + \frac{T}{8} a_{3} + \frac{T}{8} a_{4} = 0$

$\Rightarrow 4 a_{1} + 2 a_{2} + a_{3} + a_{4} = 0$

A thin circular ring of mass M and radius R is rotating with a constant angular velocity 2 rads^-1 in a horizontal plane about an axis vertical to its plane and passing through the centre of the ring. If two objects each of mass m be attached gently to the opposite ends of a diameter of ring, the will then rotate with an angular velocity (in rads^-1).

Payal Gupta

By conservation of Angular momentum

L_i = L_f

$M R^{2} ω = (m R^{2} + 2 m R^{2}) ω'$

$\frac{2 M}{M + 2 m} = ω'$

$\Rightarrow$ $ω' = \frac{2 M}{M + 2 m}$

A body of mass M at rest explodes into pieces, in the ratio of masses 1 : 1: 2. Two smaller pieces fly off perpendicular to each other with velocities of 30 ms^-¹ and 40 ms-¹ respectively. The velocity of the third piece will be:

alok kumar singh

Let ‘v’ be the velocity of third piece

com along x-axis

M × 0 = M₁v_x + M₃v’_x

$\Rightarrow 0 = M_{1} \times 30 + M_{3} v' x$

$v_{x} 1 = \frac{- M_{1}}{M_{3}} \times 30$

$\frac{- 1}{2} \times 30$

$v_{x}^{1} = - 15 m / s e c$

Com along y-a

Let ‘v’ be the velocity of third piece

M × 0 = M₁v_x + M₃v’_x

$\Rightarrow 0 = M_{1} \times 30 + M_{3} v' x$

$v_{x} 1 = \frac{- M_{1}}{M_{3}} \times 30$

$\frac{- 1}{2} \times 30$

$v_{x}^{1} = - 15 m / s e c$

Com along y-axis

M × 0 = M₂v_y + M₃v’_y

v_y = $\frac{- M_{2}}{M_{3}} v_{y}$

v_y = $\frac{- 1}{2} \times 40$

v_y = -20m/sec

^{$\vec{v} = - 15 \hat{i} - 20 \hat{j}$}

v = $\sqrt[]{1 5^{2} + 2 0^{2}} = \sqrt[]{225 + 400} = 25 m / s e c$
