Weightof a person inside the lift while at rest is 50 N. What it the weighthe feelswhen liftmoves up with an acceleration of 9.8 ms^(-2) .

Answer»

Solution :R= m(g+a) ( ` R to `Apparent WEIGHT )
mg= 50 N
ma= 50 N
R = mg + ma = 50 +50
R= 100 N
Here Apparentweight (R) is greaterthan the acutal weight mg(=W)
