A) \[mg\,sin\,\theta \]
B) \[\frac{{{p}^{2}}{{t}^{2}}}{m}\]
C) zero
D) \[\frac{{{p}^{2}}{{t}^{2}}}{2m}\]
Correct Answer: B
Solution :
Mass of man m = 80 kg Acceleration of lift = 5 m/s When lift is moving upwards, the reading of weighing scale will be equal to R. The equation of motion gives \[1:5:3\] \[{{(Kg)}^{1/2}}\] \[{{(Kg)}^{-1/2}}\] \[{{(Kg)}^{2}}\]
