Particle is projected along a rough horizontal table, its path must be : (assuming only gravity and contanct force due to the table acting).

A chain lies on a rough horizontal table. It starts skidding when one fourth of it’s length hangs over the edge of the table. The coefficient of static friction between the chain and the surface of the table is

Assertion :- In projectile motion a particle is projected at some angle from horizontal. At highest point of its path radius of curvature is least. At highest point of path normal acceleration of projectile is equal to acceleration due to gravity.

A horizontal force of 20 N is applied to a block of mass 4 kg resting on a rough horizontal table. If the block does not move on the table, how much frictional force the table is applying on the block. What can be said about the coefficient of static friction between the block and the table? Take g=10m/s^2 .

A horizontal force of 20 N i sapplied to a block of mass 4 kg resting on a rough horiozontal table. If the blcok does not move on the table, how much fricrtional force the table is applying on the blockgt What can be said about the coefficient of static friction between the block and the table? Take g=m/s^2 .

A block is pulled a distance x along a rough horizontal table by a horizontal string. If the tension in the string is T, the weight of the block is W, the reaction is N and frictonal force is F. Write down expressions for the work done by each of these forces.
