Explanation:
for 6kg body
a downward
T-6gsin(¤)=6(-a)
teta is30°
SIN30=1/2
T-3g=-6a
T=-6a+3g........(1)
for 4kg dody
a is upward
T-4g=4a
T=4a+4g.........(2)
tension is same for both
equating 1 and 2
4a+4g=-6g+3g
g=-10a
10=-10a
a=-1 m/s^2
negative indicates downward motion
substitute a=-1 in 2
T=-4+40
T=36N
