A) \[\frac{50}{9.8}N\]
B) \[50\times 9.8N\]
C) 50 N
D) zero
Correct Answer: D
Solution :
Mass of the boy \[m=50\] Acceleration of lift (downwards) \[a=9.8\text{ }m/{{s}^{2}}\] The apparent weight of the boy when the lift is moving downwards \[W=m(g-a)=50(9.8-9.8)=0\]You need to login to perform this action.
