A) \[m\sqrt{{{g}^{2}}+{{a}^{2}}}\]
B) \[m\sqrt{{{g}^{2}}+{{a}^{2}}}-ma\]
C) \[m\sqrt{{{g}^{2}}+{{a}^{2}}}+ma\]
D) \[m\left( g+a \right)\]
Correct Answer: C
Solution :
[c] (Force diagram in the frame of the car) Applying Newton?s law along string \[\Rightarrow T-m\sqrt{{{g}^{2}}+{{a}^{2}}}=ma\] \[\text{or }T=m\sqrt{{{g}^{2}}+{{a}^{2}}}+ma\]You need to login to perform this action.
