A) \[\frac{Mgx}{2}\]
B) \[\frac{Mgx}{3}\]
C) \[\eta \]
D) function of \[2mg\,[1+{{(\eta /L)}^{2}}]\]and spring constant
Correct Answer: C
Solution :
(c.)To make Q, leave contact \[kx={{M}_{0}}g\] \[\Rightarrow \] \[x=\frac{{{M}_{0}}g}{k}\] Before coming to rest P has to fall \[x=\frac{{{M}_{0}}g}{k}\]conserving energy, we have \[mg\left( \frac{{{M}_{0}}g}{k} \right)=\frac{1}{2}k{{\left( \frac{{{M}_{0}}g}{k} \right)}^{2}}\] \[\Rightarrow \] \[m=\frac{{{M}_{0}}}{2}\]You need to login to perform this action.
