The force required to move the body up the plane will be minimum if it makes an angle with the inclined plane __________ the angle of friction.
YOUR ANSWER : ?
YOUR ANSWER : ?
The moment of inertia of a sphere of mass 'm' and radius 'r', about an axis tangential to it, is
YOUR ANSWER : ?
The total momentum of a system of masses (i. e. moving bodies) in any one direction remains constant, unless acted upon by an external force in that direction. This statement is called
YOUR ANSWER : ?
A semicircular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi circular disc and horizontal surface is µ. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will
