In the figures shown, 1 kg block is stationary while 2 kg block is being pulled with constant speed. The spring is exerting a force of 1N on the block

A

The coefficient of kinetic friction between both the blocsk is 0.1

B

if the 2kg block is suddenly stopped, 1 kg block will start moving to the left.

C

If the floor is smooth, we need to apply a force of 1N on 2 kg block to pull it with constant speed.

D

The fricition on 2kg block due to 1kg block is in the direction of spring force on 1kg block.

Text Solution

Verified by Experts

The correct Answer is:
ACD

As there is relative motion between blocks kinetic friction is acting
`muN=1N`

`muxx1xx10=1`
`rArr mu =0.1 " " F_(k)=1N` as block is stationary
If 2 kg block is suddenly stopped
Static friction will act and block is in equilibrium

If floor is smooth

Should be applied

Each of the blocks shown in figure has mass 1 kg. The rear block moves with a speed of 2 m/s towards the front block kept at rest. The spring attached to the front block islight and has a spring constant 50 N/m. find the maximum compression of the spring.

A block of mass m, lying on a smooth horizontal surface, is attached to a spring (of negligible mass) of spring constant k. The other end of the spring is fixed, as shown in the figure. The block is initally at rest in its equilibrium position. If now the block is pulled withe a constant force F, the maximum speed of the block is :

A block of mass sqrt(3)//10kg is placed on a rough horizontal surface as shown in the figure. A force of 1N is applied at one end of the block and the block remains stationary. The normal force exerted by the sruface on the block acts(g=10 m//s^(2) )
