A) 510 N
B) 480 N
C) 490 N
D) 500 N
Correct Answer: D
Solution :
Given that mass of boy m = 50 kg Weighing machine is moving upwards with uniform speed, so acceleration of machine will be zero, a = 0. \[T-mg=ma\] \[T-50g=50\times a\] but \[a=0\] \[T=50\,g\] \[T=50\times 10\] \[T=500\,N\]You need to login to perform this action.
