Hey everyone, welcome back.
00:01
In this question we are given that there is an elevator and in this elevator there is a person.
00:07
Now, mass of the elevator is given in question as 400 kg and mass of this particular person is given as 100 kg.
00:15
In this question we have to find out the weight of the person.
00:19
Okay, and this particular elevator is accelerating in the upward direction with acceleration a that is equals to 2 meter per second square.
00:28
Now if i draw free body diagram of this particular person, so there is normal force on this person in the upward direction because of this particular wing machine to measure the weight.
00:39
There will be weight force in the downward direction which is mg and because of acceleration of the frame there will be pseudo force in the opposite direction.
00:49
Okay, so if this is accelerating in the upward direction, so pseudo force will be in the downward direction and that is equals to mass of the person into acceleration of the frame...
