A) \[9.80\,m{{s}^{-2}}\] downwards
B) 9.80\[m{{s}^{-2}}\] upwards
C) 1.96\[m{{s}^{-2}}\] downwards
D) 1.96\[m{{s}^{-2}}\] upwards
Correct Answer: D
Solution :
As the apparent weight increase therefore we can say that acceleration of the lift is in upward direction. \[R=m(g+a)\]Þ\[4.8\ g=4(g+a)\] Þ\[a=0.2g=1.96\ m/{{s}^{2}}\]You need to login to perform this action.
