Question

The gravitational force between two bodies is
(A). Repulsive at large distance
(B). Attractive at all places
(C). Attractive at short distances
(D). Repulsive at short distances

Answer 1

Hint: Before attempting this question one should have prior knowledge about the concept of gravitational force and remember to use the formula of gravitational force, use this information to approach towards the solution of the question.

 Complete step-by-step solution -
We know that according to the newton’s law of gravity every object or body that exist and have mass in this universe exerts force on each other the force which is experienced by the both bodies is called gravitational force and according to law of gravity F is directly proportional to $\dfrac{{{m_1}{m_2}}}{{{d^2}}}$ and the equation by which gravitational field can be calculated is given by F = $\dfrac{{G{m_1}{m_2}}}{{{d^2}}}$ Here m1 and m2 are the masses of bodies which are experiencing the gravitational force, d is the distance between two masses and G is the universal gravitational constant.
Since by the formula of gravitational force we can say that the nature of gravitational force doesn’t depend upon the distance between the objects the effect of gravitational force decreases with distance but the attractive nature of gravity remains same
So the gravitational force is attractive in nature at all places
Hence option B is the correct option.

Note: In the concept of law of gravity there is also a term named acceleration due to gravity same as gravitational force but the acceleration due to gravity states that the rate of change in the velocity of body falling from some height due to gravitational force acting on it the value of acceleration due to gravity is 9.8 $m/{s^2}$ The value of acceleration due to gravity is different at poles and equator of the earth due to shape of earth i.e. ellipse shape.
