A body of mass m is placed on a table. The earth is pulling the body with a force mg. Taking this force to be the action what is the reaction?

A book of mass 5 kg is placed on a table and it is pressed by 10 N force then normal force exerted by the table on the book is

A body of mass 10 kg is placed on rough surface, pulled by force F making an angle of 30^(@) above the horizontal. If the angle of friction is also 30^(@) , then the minimum magnitude of force F required to move the body is equal to ( take, g=10 ms^(-2) )

A body of mass 10 kg is suspended by a string and is pulled a side with a horizontal force of 49 N. Find the tension in the string, if the body is in equilibrium under these forces.

A body of mass M is pressed between two hands. Each hand exerts a horizontal force F. The net horizontal force acting on the body is

A force of magnitude 2mg(1-ay) starts acting in the vertically upward direction on a body of mass m placed on earth's surface where y is the height of the object above the ground during ascent and 'a' is a positive constant. Total height through which the body ascends is

A mass m is palced on a body of mass M. There is no friction anywhere. Force F is applied on M and it moves with acceleration a. Find the force (along x-axis) on the top body.

A body of mass 2kg is placed on a horizontal surface having kinetic friction 0.4 and static friction 0.5 . If the force applied on the body is 2.5N , then the frictional force acting on the body will be

If action force acting on a body is gravitational in nature, the reaction force

A block of mass 10 kg is placed on a rough horizontal surface of coefficient of friction 0.1. A pulling force of 100 N acts on it at 37^(@) with the horizontal. The frictional force acting on the body is ..... N.

A rigid body moves a distance of 10m along a straight line under the action of a force 5N. If the work done by this force on the body is 25 joules, the angle which the force makes with the force makes with the direction of motion of the body is:
