Force of 2 kgf is applied at one end of the spring balance kept horizontal and an equal force of 2 kgf is applied at the other end in the opposite direction, Simultaneously. Then the reading on the spring balance is

A mass of 4 kg rests on a horizontal plane. The plane is gradually inclined until an angle theta=15^@ with the horizontal and the mass begins to slide. What is the coefficient of static friction between the block and the surface ?

A block of mass 10 kg kept on a rough horizontal surface can be maintained in uniform motion in a straight line when the force of 50 N is applied to the body in the direction of it’s motion. Find the coefficient of kinetic friction between the surfaces.；

A metal plate 100 cm^2 in area rests horizontally on a layer of oil 2 mm thick.A force of 0.1 N applied to the plate horizontally keeps it moving with a uniform speed of 2cm/s . Find the viscosity of oil.
