Ablock is on rough surface.is the maximum force applied so that the block does not move is equal to the minimum force applied to just move the block?
A block resting on a horizontal surface and suppose a force is applied to it and still the body is not moving then, friction force is equal to applied force...

A body of weight w1 is suspended from the ceiling of a room through a chain of weight w2The ceiling pulls the chain by a force
Correct option (c) Explanation: The ceiling pulls the chain with a force equal to the sum of weights of chain and the body. So the pulling force = (w1 + w2)

A 5.0 cm long straight piece of thread is kept on the surface of water. Find the force with which the surface on one side of the thread pulls it.
Length of the thread, L = 5.0 cm =0.05 m The surface tension of the water, S = 0.076 N/m Hence the force of surface tension on one side of the thread...

A horizontal force of 600N pulls two masses 10kg and 20kg (lying on a frictionless table) connected by a light string.
If the 20 kg mass is pulled, 600 - T = 20a, T = 10a a = 20ms-2, T = 200N If the 10kg mass is pulled, a = 20ms-2, T = 400N
