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: D
Solution :
Downward force on pulley \[=(M+m)g\] Leftward force on pulley = tension in the string \[=Mg\] But two forces are perpendicular, therefore the resultant force \[=\sqrt{{{(M+m)}^{2}}+{{M}^{2}})}g\]You need to login to perform this action.
