Question

A force of 10 N displaces a body by a distance of 3 m at an angle 90° to its own direction. Find the amount of work done.​

Answer 1

Answer:

W= FScos theta

W= 10×3×cos90

W=10×3×0

hence work done is zero

Answer 2

Answer:

0

Explanation:

workdone = f x s x cosФ                    

                 = force x displacement x cosФ                            Ф = 90°

=whenever f and d are in same direction

i.e. forming a angle of 90°

then Ф =0°

therefore here workdone will be 0
