Question

Two electrons each of mass 9.1 into 10 to the power minus 31kg are at a distance of 10 to the power minus 10 metre calculate the gravitational force between them

Answer 1

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
