If a small asteroid named ‘B612’ has a radius of only 20 m and mass of 1 × 104 kg, what is the acceleration due to gravity on its surface?

Acceleration produced in the motion of a body under the effect of gravity is called acceleration due to gravity.

It is a vector quantity and it's SI unit is m/s².

It is usually denoted by the symbol g.

Formula of Acceleration due to Gravity:

G → Universal Gravitational Constant

M → Mass of the Asteroid (1 × 10⁴ kg)

R → Radius of the Asteroid (20 m)

By substituting values in the equation, we get:

Acceleration due to gravity on the surface of small asteroid named ‘B612’ =

a and b sometimes have a positive value

b.a device that inputs heat into a cool object
