Question

write the expression for the acceleration due to gravity of a body of mass m on a planet of mass m which direction does it act​

Answer 1

Answer:

G Mm/d^2 please follow me sister

Answer 2

The expression for acceleration due to gravity of a body o mass "m" on a planet of mass "M" is given by, g = $\frac{GM}{r^2}$. This acts in a downward direction.

• Where "G" is the gravitational constant ( G = 6.67408 × $10^{-11}$ $Nm^2/Kg$), "M" is the mass of the earth, and "r" is the radius of the earth.
• The acceleration produced in the motion of the body under the gravitation is called acceleration due to gravity. It is denoted as "g". Acceleration due to gravity is zero at the center of the earth because when the body is already present at the center then there is no need for any force to pull towards the center again.
