Question
Three man A, B and C mass 40 kg, 50 kg 60 are standing on a plank pf mass 90 kg, which is. kept on a smooth horizontal plane. If A & C exchange their positions then mass B will shift
Options
A.1/3 m towards left
B.1 / 3 m towards right
C.will not move w.r.t. ground
D.5 / 3 m towards left
Solution
Let xp = x shift of plank to the right
