The potential energy function associated with the force `vecF=4xyhati+2x^2hatj` isA. (a) `U=-2x^2y`B. (b) `U=-2x^2y+const ant`C. (c) `U=2x^2y+const ant`D. (d) Not defined |

Answer» Correct Answer - B `dU=-vecF.ds=-vecF.(dxhati+dyhatj)` Also by reverse method using `F_x=(delU)/(delX)` and `F_y=-(delU)/(delY)` only option(b) satisfies the criteria. |
