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» 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. |
