Answer:
The Force that will exist between the 2 electrons will be 552.3427*10⁻⁵³ N.
Explanation:
Given,
Mass of two e⁻ = 9.1*10⁻³¹ kg
Distance between them = 10⁻¹⁰m
Gravitational Constant (G) = 6.67*10⁻¹¹ Nm²/kg²
= Force = Gm₁m₂/r²
= (6.67*10⁻¹¹) . (9.1*10⁻³¹) . (9.1*10⁻³¹) / 10⁻¹⁰ . 10⁻¹⁰ N
= (6.67*9.1*9.1) . 10⁻¹¹⁻³¹⁻³¹ / 10⁻¹⁰⁻¹⁰ N
= 552.3427 . 10⁻⁷³ / 10⁻²⁰ N
= 552.3427 . 10⁻⁷³⁺²⁰ N
= 552.3427*10⁻⁵³ N
Hope this helps.
