Question

two bodies mass of 2kg and 6kg find the acceleration and Tension in the string​

Answer 1

Answer:

ANSWER

Since 6kg is heavier than 4 kg so it will accelerate down while 4 kg will accelerate up

So the equation of net force on 6kg is given as

6× 10− T= 6a

equation of net force on 4kg is given as

T− 4× 10= 4a

now add the above two equations

6× 10− (4× 10)= (6+ 4)× a

60 - 40 = 10a

a = 2m/s

2

So 6 kg will accelerate downwards while 4 kg will accelerate upwards

with acceleration 2 m/s

2

now in order to find the tension force

T− 4× 10= 4× 2

T = 48N

So the tension in the string is 48 N
