Question

find the force of gravitation acting between two planets of mass 8x1022 Kg and 5x1025 Kg which are
2x1015 m away from each others​

Answer 1

Answer:

Given,

Mass 1 (m₁) = 8.0*10²² kg

Mass 2 (m₂) = 5.0*10²⁵ kg

Radius (r) = 2.0*10¹⁵ m

Gravitational Constant (G) = 6.67*10⁻¹¹ Nm²kg⁻²

Force (F) = Gm₁m₂/r²

= [6.67*8.0*5.0*10²²⁺²⁵⁻¹¹] / 2.0*10¹⁵

= 266.8 * 10³⁶ / 2.0*10¹⁵

= [266.8/2.0] * 10³⁶⁻¹⁵

= 133.4*10²¹ N

or,

= 1.334*10²³ N

I hope this helps.
