A block is placed on a rough horizontal plane. Three horizontalforces are applied on the block as shown in the figure. If the block is in equilibrium, find the friction force acting on the block.

A particle of mass m is tied to light string and rotated with a speed v along a circular path of radius r. If T=tension in the string and mg= gravitational force on the particle then actual forces acting on the particle are
