With what force one object attracts another object?

Mass of one object remains same, but of another object mass is increased 3 times than before and their distance is also increased three times. Then will the gravitational force increase or decrease?

An object is approaching a convex mirror. The ratio of the velocity of the object and that of the object image which is m times magnified is

State whether True or False : The force with which earth attracts an object near it is called gravitational force.

Two forces of the same magnitude F are at right angles to each other. The magnitude of the net force (total force) acting on the object is

State whether True or False : The force with which sun attracts an object near it is called gravitational force.

The sun and the earth both exert a gravitational force of attraction on any object on the earth's surface. The two gravitational forces are in opposite directions during noon and in the same direction at midnight. Will an object weight more at midnight ?

Which one is greater- the force of attraction of 1 kg lead on the earth or the force of attraction of the earth on 1kg lead ?

A convex lens of focal lengths 30 cm produces 5 times magnified real image of an object What is the object distance ?

On what factors the attraction between two objects depend? Explain how they depend?

if the force applied on an object is 5N and the power expended by it 20W , what is the velocity of the object ?
