A 1000kg elevator is descending vertically with an acceleration of 1.0ms-2, if the acceleration due to gravity is 10ms-2, the tension in the suspending cable is
Answer Details
The elevator is descending so the weight acts in line with the acceleration which is downwards. So according to Newton's law, mg(weight) -R (tension/reaction) = ma
