Calculate the Coulomb's force between two protons separated by `1.6 xx 10^(-15)` m.

Text Solution

Verified by Experts

Charge on proton = `e = 1.6 xx 10^(-19) C `
`implies q_1 = q_2 =1.6 xx10^(-19)C`
Distance between two protons `r=p= 1.6 xx 10xx^(-15) m`
`F=1/(4piin_0)(q_1q_2)/r^2`
`=9xx10^9xx((1.6xx10^(-19))^2)/((1.6xx10^(-15))^2)`
`= 9 xx10^9 xx10^(-38+30)`
`= 9 xx10^(1) = 90 N`
