A spring balance,which is suspended from the roof of a lift, carries a mass of 1kg at its free end. If the lift accelerates upwards at 2.5ms^-2, determine the reading on the spring balance. [g = 10ms^-2]

24.0N

12.5N

7.5N

4.0N

wrong W=m(g-a) since it z accelerating upwards

ansa is 7.5N

good explanation

T=m(g+a) when accelerating upward
T=1(10+2.5)
T=1(12.5)
T=12.5✓
