For 2kg block
F_upwards = 20 + 20 = 40 N
F_downwards = mg = 2*10 = 20 N
F_net = F_upwards - F_downwards
= 40 - 20
= 20 N
Acceleration = F_net / m
= 20 N / 2kg
= 10 m/s^2
F_upwards = 20 + 20 = 40 N
F_downwards = mg = 2*10 = 20 N
F_net = F_upwards - F_downwards
= 40 - 20
= 20 N
Acceleration = F_net / m
= 20 N / 2kg
= 10 m/s^2
