Question

the electrostatic force between two charges is 49×10^8 N how much the distance between them be decreased so that the force between them becomes double . pls solve​

Answer 1

Answer:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power). If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

so, F = k.(1/d^2)
