Answer 2

$\large\maltese\: \underbrace{{\pmb{\frak{Answer:-}}}}$

• 0 Joules
• If the force is applied perpendicularly on the body, no work is done.

$\large\maltese\: \underbrace{{\pmb{\frak{Verification:-}}}}$

we know that: -

$\\\leadsto\underline{\boxed{\sf Work\:Done_{(W)}= Force_{(F)}\times Displacement_{(S)}\times \cos(\theta)}}\bigstar$

• We are already provided with the values of force, displacement, and theta in the question which are 50 N, 2 m and, 90° respectively.
• cos 90° = 0

$\\:\implies\sf Work\:Done = FS\cos(\theta)$

$\\:\implies\sf Work\:Done = 50\times 2\times 0$

$\\:\implies\boxed{\boxed{\sf Work\:Done= 0 \:joules}}\bigstar$
