Calculate the force of gravitation due to the earth on a ball of 2kg mass lying on the floor consider the mass of the earth =6×10to the power24kg radius of the earth =6400km and universal gravitation constant G=6.7×10to the power-11Nmsquare/kgsquare

It will be 9.8 Newton On a Ball of Mass 1 kg Just Put This Formula and Take the Mass of ball as 2kg
F = G × Mass (earth) × mass (ball) / Radius^2
F = G × Mass (earth) × mass (ball) / Radius^2

Gravitational Force = -(G M1 M2)/r²
where, G is the Gravitational constant
M1 is the mass of 1st body (or object)
M2 is the mass of 2nd body (or object)
r is the distance between the 1st & 2nd body ( or object).
And negative sign represents that this direct is attractive.
Now, G = 6.7 × 10-¹¹ Nm²/kg²
M1 = 2kg
M2 = 6 × 10²⁴ kg
r = 6400 km = 6400×10³m
So, putting all the values in the formula:
F = [(6.7 × 10-¹¹Nm²/kg²)×(2kg)×(6 × 10²⁴kg)]/(6400×10³m)²
= 19.628 N
Thankyou!!!
