Hello buddy,
◆ Answer-
F = 10 dyne
◆ Explaination-
# Given-
m = 5 g
t = 2.5 s
v = 5 cm/s
# Solution-
Average force acting on the balloon is calculated by Newton's second law of motion.
F = mv/t
F = 5 × 5 / 2.5
F = 10 dyne
F = 10^-4 N
Therefore, average force acting on the balloon is 10 dyne.
*Note CGS units used here.
Hope this helps...
