Explanation:
The net force exerted on the mass is the sum of tension force and the external force of gravity.

is the tension force.
is the force of gravity.

where
is the rope's radius from the fixed point.
From the net force equation above:

Hence the tension force is 6.046N
Answer:
The vector magnitudes F and r are always postive, so the sign o W is determined entirely by the angle e between the force and the displacement.Submit Figure 1 off 1 part C
