In fig. a small block is kept on m. then

A

The acceleration of m w.r.t. ground is `F//m`.

B

The acceleration of m w.r.t ground is zero.

C

The time taken by m to separted from M is `sqrt((2lm)/(F))`.

D

The time taken by m to separted from M is `sqrt((2lM)/(F))`.

Text Solution

Verified by Experts

The correct Answer is:
B, D
Acceleration of `M,a=((F)/(M))`
`l=1/2 F/M t^(2) implies t=sqrt((2Ml)/(F))`.

Two springs, each of unstretched length 20 cm but having different spring constant k_1=1000(N)/(m) and k_2=3000(N)/(m) are attached to two opposite faces of a small block of mass m=100g kept on a smooth horizontal surface as shown in fig. The outer ends of the two springs are now attached to two pins P_1 and P_2 whose locations are shown in the figure. as a result of this, the block acquires a new equilibrium position. The block has been displaced by small amount from its equilibrium position and released to perform simple harmonic motion: then
