A particle is acted by `x` force `F = Kx` where `K` is `a( + Ve)` constant its potential mwrgy at `x = 0` is zero . Which curve correctly represent the variation of putential energy of the block with repect to `x`A. B. C. D. |

Answer» Correct Answer - B (b) WE know that `delta U = -W` for conservative forces `deltaU = - int_(0)^(x) Fdx ` or `deltaU = - int_(0)^(x) k xdx` `rArr U_(x) - U_(0) = (kx^(2))/(2)` Given ` U_(0) = 0 U_(x) = -(kx^(2))/(2)` |
