At what distance is the electrostatic force between two protons equal to the weight of one proton?

The distance between two protons is 37 cm.                    

Explanation:

The electric force between two electric charges is given by :

Here,

k is the electrostatic force

d is the separation between charges

are charges

According to given condition, the electrostatic force between two protons equal to the weight of one proton. So,

As protons are very small particle, W = m

d = 0.37 m

or

d = 37 cm

So, the distance between two protons is 37 cm. Hence, this is the required solution.
