Question

two electrons each of mass 9.1*10^-31 kg are at a distance of 10 A calculate the gravitational force of attraction between them given 1A=10^-10m

Answer 1

Explanation:

F= GMm/d²

= Gm²/d² ………[∵ M = m]

= G (m/d)²

= (6.67 × 10^-11 N m^2/kg^2) × [(9.1 × 10^-31 kg) / (10 × 10^-10 m)]^2

= 5.52 × 10^-53 Newtons

∴ Gravitational Force between them is 5.52 × 10^-53 Newtons
