An elevator accelerates upward with acceleration a. The elevator has a mass M, and inside the
elevator are two people, each with a mass m. The tension force in the rope pulling the elevator
upward is T_(2).
When one person accelerates with the elevator at the same acceleration a, the tension force is T_(1).
What is T_(2)-T_(1) ?
The options are:
AT_(2)-T_(1)=mg
BT_(2)-T_(1)=ma
CT_(2)-T_(1)=2mg
DT_(2)-T_(1)=2ma
ET_(2)-T_(1)=m(a-g)
FT_(2)-T_(1)=m(g-a)
GT_(2)-T_(1)=m(a+g)
HT_(2)-T_(1)=2m(a-g)
IT_(2)-T_(1)=2m(g-a)
JT_(2)-T_(1)=2m(a+g)
