Question

a body gets displaced through a distance of 5m under the action of force 10 N acting at a right angle to the displacement. work done will be

Answer 1

Answer:

$work \: done = 0 \: joules.$

Explanation:

$force = f= 10 \: newton \\ \\ displacement = s= 5m \\ \\ \cos(90) = 0 \\ \\ therefore \: \: \: \: work \: done = fs \cos(90) \\ \\ = 10 \times 5 \times 0 \\ \\ = 0 \: joules.$
