-- A person is standing on a weighing machine and observes that the reading is 60 kg, then suddenly jumps upward and observes that reading goes to 70 kg. Then his maximum upward acceleration is
A
g/6
B
g/7
C
g/3
D
g/2
Explanation
Apparent weight N = m(g + a). Initially N1 = mg = 60g. Finally N2 = m(g+a) = 70g. Dividing: (g+a)/g = 70/60 => 1 + a/g = 7/6 => a/g = 1/6 => a = g/6.
