Question

Answer the below question about gravitational force.

Answer 1

Answer :

option 1

Explanation :

Gravitational force is a universal attractive force in which each object tends to pull the another towards it by some force proportional to the product of masses and inverse of squares of distance joining the centres of the two bodies .

Mathematically , it can be expressed as :

$\tt F = G \dfrac{Mm}{R^2}$

Gravitational force is a central force , i.e. acts between the centre . Irrespective of the masses of the bodies , the two bodies will attract each other with same force , according to Newton's third law of motion .

In figure 1 , both sun and the moon are attracting each other which correctly explains the gravitational pull between them .

In figure 2 , repulsion is shown between sun and moon . Since gravitational force is attractive , this is a wrong depiction of the situation .

In figure 3 , gravitational force is acting downwards in the space . Since gravitational force is a central force , this depiction is also wrong .

In figure 4 , only sun is shown attracting the moon and moon falling into it . This case. cannot stand because both bodies exert equal attractive force .

Hence , figure 1 is the correct explanation.
