In above question it is given that
M=80kg
A=5m/s2
Since we know that weighing scale measures N/G (where N is normal and G is gravitational constant I.e 10
Now we know that mass and acc. Of lift as well as acc. Due to gravity
Therefore normal on weighing scale =
N= force exerted by gravity+ force due to acc.
=> N = MG + MA
=> N = 80(10)+80(5)
=> N = 800+400
=> N = 1200
And that our answer 1200 N
