〽⤵⤵Actually welcome to the concept of the Work - Power And Energy ....

〽⤵⤵Basically we can see here ...there is no velocity for the body ...while climbing the the height thus ...the Maximum Potential Energy gained by it is given as

〽⤵⤵P.E. = Mgh. ...
〽⤵P.E. = (50) (9.8) (100)
========》 49000 JOULES ....

〽⤵⤵Thus the Potential Energy gained is 4.9 × 10^4 j.....

〽⤵⤵In this case the Work done = Potential Energy gained ...

〽⤵⤵thus Work done = 4.9 × 10^4 ...j
