In certain position $X$, kinetic energy of a particle is $25 \mathrm{~J}$ and potential energy is $-10 \mathrm{~J} .$ In another position $Y$, kinetic energy of the particle is $95 \mathrm{~J}$ and the potential energy is $-25 \mathrm{~J}$. During the displacement of the particle from $X$ to $Y$ (a) Net work done by all the forces is $-70 \mathrm{~J}$. (b) Work done by the conservative forces is $-15 \mathrm{~J}$. (c) Work done by all the forces besides the conservative forces is $55 \mathrm{~J}$. (d) Work done by the conservative forces equals work done by the non-conservative forces.
