A) \[\sqrt{2}mg\]
B) \[\sqrt{2}mg\]
C) \[[\sqrt{{{(M+m)}^{2}}+{{m}^{2}}}]g\]
D) \[[\sqrt{{{(M+m)}^{2}}+{{M}^{2}}}]g\]
Correct Answer: C
Solution :
Force on the pulley by the clamp = resultant of T (M + m) g and mg acting along horizontal and vertical directions respectively, \[=\sqrt{{{[(M+m)g]}^{2}}+{{(mg)}^{2}}}\] \[=[\sqrt{{{(M+m)}^{2}}+{{m}^{2}}}]g\] Hence, the correction option is [c].You need to login to perform this action.
