Find the ratio of the electric and gravitational forces between two protons.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Let the distance between two protons - r ltbgt Then `f_e = 1/ (4pi epsilon_0) xx q^2/r^2`
` and ` F_g= (Gqm^2)/r^2`
`:. F_e/F_g= 1/(4pi epsilon_0) xx q^2/r^2xx r^2/Gm^2`
`= (9xx10^9xx1.6xx1.6xx10^-38)/(6.67xx10^-11xx1067xx1067xx10^-54)`.
