A block of mass 4 ka placed on a horizontal
surface is connected to another mass of 3 kg by
a massless inextensible string going over a pulley
as shown.A force ofF = 50 N is applied
horizontally on A as shown. At the instant,
e is 60° and the blocks are at momentary rest.
The tension in the string is (take g = 10 m/s?)
88.
