372231 Two blocks \(A\) and \(B\) of masses \(3 \mathrm{~m}\) and \(\mathrm{m}\) respectively are connected by a massless and inextensible string. The whole system is suspended by a massless spring as shown in figure. The magnitudes of acceleration of \(A\) and B immediately after the string is cut, are respectively

372232 Assertion: A man and a block rest on smooth horizontal surface. The man holds a rope which is connected to block. The man cannot move on the horizontal surface.

Reason: A man standing at rest on smooth horizontal surface cannot start walking due to absence of friction (The man is only in contact with floor as shown).

372233 A body of the mass \(50 \mathrm{~kg}\) is suspended using a spring balance inside a lift at rest. If the lift starts falling freely, the reading of the spring balance is :

372234 Two blocks are connected over a mass less pulley as shown in fig. The mass of block \(A\) is \(10 \mathrm{~kg}\) and the coefficient of kinetic friction is 0.2. Block A slides down the incline at constant speed. The mass of block \(B\) in \(\mathrm{kg}\) is:

372235 Three blocks of masses \(m_{1}, m_{2}\) and \(m_{3}\) are connected by massless strings, as shown, on a frictionless table. They are pulled with a force \(T_{3}=40 \mathrm{~N}\).
