Two bodies of masses `3kg` and `2kg` are connected by a spring balance Two forces of `10N` and `5N` are applied on the blocks as shown The reading of the spring balance (in newton) would be
.

Text Solution

Verified by Experts

The correct Answer is:
`7`
Total mass, `m = m_(1) + m_(2) = 3 + 2 =5kg`
Net force `F = F_(1) -F_(2) = 10 -5 =5N`
Acceleration `a = (F)/(m) = (5)/(5) =1m//s^(2)` along 10 N force
Reading of spring balance `= F_(1) -m_(1)a`
`=10 -3 xx 1 =7N` .

Two blocks of mass 10 kg and 2 kg are connected by an ideal spring of spring constant 1000 N/m and the system is placed on a horizontal surface as shown. The coefficient of friction between 10 kg block and surface is 0.5 but friction is assumed to be absent between 2 kg and surface. Initially blocks are at rest and spring is unstretched then 2 kg block is displaced by 1 cm to elongate the spring then released. Then the graph representing magnitude of frictional force on 10 kg block and time t is : (Time t is measured from that instant when 2 kg block is released to move)

A man of mass 60 kg is standing on a spring balance inside a lift. If the lift falls downwards, then the reading of the spring balance will be:-

Two blocks of mass 10 kg and 2 kg are connected by an ideal spring of spring constant K = 800 N//m and the system is placed on a horizontal surface as shown. The coefficient of friction between 10 kg block and surface is 0.5 but friction is absent between 2 kg and the surface. Initially blocks are at rest and spring is relaxed. The 2 kg block is displaced to elongate the spring by 1 cm and is then released. (a) Will 10 kg block move subsequently? (b) Draw a graph representing variation of magnitude of frictional force on 10 kg block with time. Time t is measured from that instant when 2 kg block is released to move.
