Question

The two bodies having masses 10kg and 15 kg are 1m apart find force between them

Answer 1

Given;

• m1 = 10kg
• m2 = 15kg
• r = 1m

Therefore gravitational force acting between them ( F ) ;

• F = G × ( m1m2/r² )
• F = 6.67 × 10^-11 ( 15×10/1² )
• F = 6.67 × 10^-11 ( 150 )
• F = 1000.5 × 10^-11
• F = 10005 × 10^-12 Newton or 10005 × 10^-12 N

Answer 2

Solution:

m1=100kg

m2=1000kg

r=1m

Let x be the distance of point P from 100kg where the resultant gravitational Intensity is zero.

Gravitational Intensity at P due to body of mass 100kg is equal and opposite to that of object of mass 10,000kg

Gx100/x²=Gx10000/(1-x)²

(1-x)²=100x²

10x =1-x

11x=1

x=1/11m

Therefore at this point gravitational field intensity will be zero.
