TS EAMCET 5-Aug-2021 Shift 1 Question Paper

As we know that,
In case of non-conservative force, work done depends on path instead of only initial and final positions and for closed path, displacement will not be zero.
Work (W)= Force (F)× Displacement (s)‌cos‌θ
where, s≠0m
∴‌‌W≠0J
Hence, non-conservative work done will not be equal to zero for closed path.
