Two blocks connected by a massless string slide down an inclined plane having angle of inclination 37º. The masses of the two blocks are M1 = 4 kg and M2 = 2 kg respectively and the coefficients of friction 0.75 and 0.25 respectively-

The common acceleration of the two masses is `1.3 ms^(-2)`
b, The tension in the string is 14.7 N
c The common acceleration of the two masses is `2.94 ms^(-2)`
d, The tension in the string is 5.29N
