Two blocks of mass 2kg and 4kg are accerlerated with same acc by a force 10 N as shown in fig on a smooth horizontal surface . then the spring force between the two blocks will be ( spring is massless) ?
1) 5N 2) 10N 3) 10/3N 4) 5/3N

Acceleration of 2kg object
a = T / 2
Acceleration of 4kg object
a = (F - T) / 4
a = (10 - T) / 4
It is said that both are moving with same acceleration.
Therefore
T / 2 = (10 - T) / 4
2T = 10 - T
T = 10/3 N
(3) is the correct option.
