Question

A brass ball is hanging from a stiff cotton thread. Draw a neat labelled diagram showing the forces acting on the brass ball and the cotton thread.
​

Answer 1

Answer:

Let the mass of the brass ball be m. So a gravitational force mg acts the ball in the downward direction.

A tension force T acts on the ball in the upward direction to make the ball to remain in equilibrium.

For equilibrium :

T=mg

Answer 2

ball in the downward direction.

A tension force T acts on the ball in the upward direction to make the ball to remain in equilibrium.

For equilibrium :

T=mg
