Consider the following distinct forces:
1.a downward force of gravity.
2.a force exerted by the channel pointing from q to o.
3.a force in the direction of motion.
4.a force pointing from o to q.
which of the above forces is (are) acting on the ball when it is within the frictionless channel at position 'q'.

1 and 2

Explanation:

It is given that, force exerted by air is negligible in any way.

Also, it is given that channel is in the shape of a segment of a circle with its center at O.

When it is within the frictionless channel at position 'Q',

A gravity exerts force on the ball in the downward direction. On the other hand, the channel pointing from Q to O also exerts a force on the ball.

However, there is no any force in the direction of motion. On the other hand, he channel pointing from O to Q does not exert a force on the ball.
