Question

The ratio of electrostatic and gravitational force acting between electron and proton separated by a distance 5 xx 10^(-11)m, will be (charge on electron = 1.6 xx 10^(-19)C, mass of electron = 9.1 xx 10^(-31) kg, mass of proton = 1.6 xx 10^(-27) kg, G = 6.7 xx 10^(-11) N - m^(2)//kg^(2))

Answer 1

Answer:

For Electrostatic force Fe=(q_1q_2)/r^2

and For Gravitational force Fg=(-GMm)/r^2

use this formula and then do Fe/Fg

Explanation:

q_1=charge of electron

q_2=charge of proton

r=5×10^-11m

M=1.6×10^-27 kg

m=9.1×10^-31 kg
