A spring of spring constant k placed horizontally on a rough surface is compressed by a block of mass m placed on the surface so as to store maximum potential energy (U) in the spring. The coefficient of friction between the block and the surface is
- \(\sqrt{\frac{2 \mathrm{~kL}}{5 \mathrm{mg}}}\)
- \(\sqrt{\frac{2 \mathrm{kU}}{3 \mathrm{mg}}}\)
- \(\frac{\sqrt{2 \mathrm{kLU}}}{\mathrm{mg}}\)
- \(\frac{\sqrt{\mathrm{kL}}}{\mathrm{mg}}\)
Answer
(C) 2 kLU mg
