Answer :

On increasing the value of angle between force and distance, the value of Cos θ decreases to zero when θ=90.Therefore, work done decrease as angle increase, work done is 0 when θ = 90 and work done is negative when angle further increases.

Cos θ reduces further to –1.


Therefore, work done decrease as angle increase, work done is 0 when θ=90 and work done is negative when angle further increases.
