★Hey there★
Just keep one concept in mind, if escalator is moving upwards, then mass acceleration is in favour of mass. what I mean to say is that mass will increase by ma where a is the acceleration of escalator.
Weight=Mass*Acceleration
mg+ma
=m(g+a)
★HOPE IT HELPS★

Hi friend
It is a general concept and you must be known that ,if the elevator (or) lift moves upward with carrying of mass m then the mass is favours with the gravity.
:- w= mg+ma
W= m(g+a).
Note:- If the lift or elevator moves downward with the mass m then the weight becomes
W= mg-ma
W= m(g-a).
Hope this helped you a little!!!

saka but the correct answer is 3,but how?
if you explain it...
Here it is retarding upward
So the condition mg-ms is followed
And the gravity is cancelled
but answer is 3
ok.
