Question

Calculate the gravitational force between a q0 kg and 20 kg ball placed at a seperation of 5m

Answer 1

Answer:

$4.8 \times {10}^{ - 13} newton$

Explanation:

Given,

m1=90kg, m2=20kg, and r=5m

Now,

we know that, F = Gm1.m2/r²

= (6.67x10-¹¹)x90x20/5²

= (6.67x10-¹¹)x18x4

= 480.24x10-¹¹N

= 4.8024x10-¹³N

≈ 4.8x10-¹³N
