Question

If the angle between force and displacement is 0, then for what value of 0 is work done zero
70⁰
90⁰
0⁰
60°​

Answer 1

$\huge{\underline{\underline{\underline{\sf{\pink{ﾑɳรᏇɛƦ \: ࿐}}}}}}$

If cosθ=1, maximum amount work can be done on the body i.e. if θ=0 or the directions of F and s are parallel. If cosθ=0 then the work done on the body will be zero i.e. when the angle between the force and the displacement is 90°.

If cosθ=0 then the work done on the body will be zero i.e. when the angle between the force and the displacement is 90°
