Question

Three 5.00-kg spheres of negligible size are located at A, B and C shown in the figure. The magnitude of the net gravitational field is zero at

• A. the centre of mass of the system
• B. the midpoint of the line joining A to C
• C. Some point for x>0 y>0
• D. None of the above

Answer 1

The correct option is A the centre of mass of the system

Gravitational field will be zero at some point $x>0,y>0$

and at their centre of mass

Hence,

option $\left(A\right)$ is correct answer.
