Question

Which would require a greater force - accelerating a 10 g mass at m/s^2 or a 20 g mass at 2 m/s^2 ??​

Answer 1

Answer:-

1) In first case:-

Force, F = m × a

=$\frac{10}{1000}$kg × $5 m/s^2$

= 0.05 N

2) In second case:-

Force, F =$\frac{2}{1000}$kg × $2 m/s^2$

= 0.04N

Thus, a greater force of 0.05 N is required for accelerating a 10 g mass.
