Question

a ball of mass 500 g kept near the earth's surface will attract the earth with a force of

Answer 1

there will be only gravitAtional force action on the ball
thus F= 500g×10m/s^2

5000×10^-3
gives us 5N


hope this will help u bro

Answer 2

Hey there!

We know,
F =  mg
where,
F = force
m = mass
g = gravitational constant (9.8 m/s^2)

ATQ,

mass = 500 g = 0.5 kg
gravitational constant = 9.8 m/s^2

Put the values:

F = mg
F=0.5 * 9.8
F=4.90 Newton

Hope it helps you!
