The earth of mass =6 10²⁴ ~kg revolves around the sun with an angular velocity of 2 10⁻⁷ rad / s in a circular orbit of radius 1.5 10^8 ~km . The force exerted by the sun on earth is :

Step-by-step solution

Here: Mass of earth M_e=6 10²⁴ ~kg Angular velocity of earth =2 10⁻⁷ rad / s Radius of circular orbit aligned R & =1.5 10^8 ~km & =1.5 10¹¹ ~m aligned Force exerted on the earth by the sun is given by aligned F & =M_e R ^2 & =6 10²⁴ 1.5 10¹¹ (2 10⁻⁷ )^2 & =36 10²¹ ~N aligned
