A body has weight 600N on the surface of the mars then what is its mass on the same place.

Explanation:

Given:

Weight = W = 600 N

Acceleration due to gravity = g = 3.7 m/s²

Required:

Mass = m = ?

Formula:

W = mg

Solution:

For m, it'll be

=> m = W/g

=> m = 600/3.7

=> m = 162.16 kg

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

your answer is, orbit around the nucleus
