Question

the mass of the sun is 2 into 10 to the power 30 kg and that of the Earth is 6 into 10 to the power 24 Kg if the average distance between the sun and the earth is 1.5 into 1l0 to the power 11.calculate the force exerted by the sun on the earth and also by the earth on the sun.​

Answer 1

Given

_____________________________

Mass of the Sun = 2 * 10 ³⁰

Mass of the Earth = 6 * 10 ²⁴

Average Distance between the sun and the earth is = 1.5 * 10 ¹¹

____________________________

So the distance will be ,

F = G * M * m / d²

F = 6.7 * 10 -¹¹ * 2* 10 ³⁰ * 6* 10 ²⁴ / (1.5 * 10 ¹¹)²

F = 3.57* 10 ²²

___________________________

Some formula to learn :-

Distance = Speed * Time

Speed = Distance / Time

Time = Distance / Speed

Force exerted by an object is = Mass of the object * Acceleration .
