suppose acceleration of the 5 kg block ‘a’ the acceleration of the 10 Kg block will be ‘2a’. if the tension in 5Kg string is T then in 10Kg block tension will be 2T :
so applying the Newton,s law on 5Kg block:
T – 5gsin30 = 5a............................................................................................................(1)
applying the Newton,s law on 10Kg block:
10g – 2T = 10a ..................................................................................................................(2)
solving equation (1) and (2)
15a = 5g
a = g/3 = 3.3 m/s-2

Force due to gravity on any mass ‘M’ is always Mg.
so gravitational force on 5kg block will be 5g = 5x10 = 50 newton
