Answer:
Step-by-step explanation:
Since, the force of gravity is,
Where,
G = gravitational constant,
M = mass of earth,
m = mass of the particle,
r = distance of particle from centre of the earth,
∵ 7500 km = meters
9400 km = meters
Thus, work done by the force of gravity,
Answer: m Angle a + 60° + 55°=180°
