Question

The electrostatic force between two charges is similar to the gravitational force between two masses, based on all of the following features except for

Force depends on the product of the entities

Force is inversely proportional to the square of the distance between the two entities

The proportionality constant is independent of the magnitude of the entities

There is no exception. All of the above are true.

None of the above is true

Answer 1

Electrostatic force is given by:

F1 = kq1q2/r^2

Gravitational force is given by:

F2 = Gm1m2/R^2

Option A is true as we can see that F1 depends on product of q1*q2 and F2 depeds on product of m1*m2

Option B is true as we can see that both F1 and F2 are inversely proportional to the square of distance

Option C is true as we can see that both k and G are independent of value of q or m

Since q = 9*10^9 & G = 6.67*10^-11

So

Correct option is D. There is no exception. All of the above are true.
