Question

If the angle between force and distance is 90° then the work done is

Answer 1

$\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}$

Actually Welcome to the concept of Work done.

We know that,

==> Work done = F. s Cos@

here, @ = angle = 90°

so we substitute to get as,

==> W = F. s Cos(90°)

since, cos(90°) = 0

==> thus the Work done is ZERO.
