Question

Which force cannot act from a distance​

Answer 1

Answer:

The force of gravity cannot act at a distance.

Explanation:

gravitational force is always attractive in nature irrespective of the distance and mass of bodies.

given by  

R  

2

 

GMm

​  

 

this decreases with distance but can never be zero.( it can be negligible as mass is small and distance is large but can never be zero)

Answer 2

Answer:

force of gravity

Explanation:

According to Newton's gravitational law,  the force on mass m due to gravity is F=  

r  

2

 

GMm

​  

 

Thus, the force of gravity depends on the distance r. Hence, the force of gravity can act for a finite distance.
