Question

give solution please​

Answer 1

Answer:

Component of 60N on the 3kg block = 60Sin¤ = 30N

Component of 18N on the 1kg block = 18Sin¤ = 9N

Force on individual blocks due to gravity -

3Kg = 3gSin¤ = 15N

2Kg = 2gSin¤ = 10N

1Kg = 1gSin¤ = 5N

Net force = Downward force - Upward force = (9+15+10+5) - 30 = 9N Downward

Net acceleration = 9N/6Kg = 3/2m/s^-2

Normal reaction between 2Kg and 1Kg blocks = 9- (3×3/2 - 2×3/2) = 9 - 7.5 = 1.5N

hope this will help you
