A block of mass kept on a smooth horizontal surface is pulled by a rope of length by a horizontal force of applied to the other end. If the linear density of the rope is the force acting on the block is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Given, Mass of block M=48 kgLinear density of string λ=0.5 kg m-1Length of string l=4 mForce applied F=25 NTotal mass of the system m=M+λl=50 NNet acceleration of system asys=Fm=2550=0.5 m s-1Suppose Tension at a point connecting end of string with block is T.From the F.B.D. of…
