Which would require a greater force - accelerating a 10 g mass at 5 m/ `s^(2)` or 20 g mass at 2 m/`s^(2)`?

Which would requires a greater force: accelerating a 2kg mass at 5m//s^(2) or a 4kg mass at 2m//s^(2) ?

Which would requires a greater force: accelerating a 2kg mass at 5m//s^(2) or a 4kg mass at 2m//s^(2) ?

Which would require a greater force-accelerating a 2 kg mass at 5ms^-2 or a 4 kg mass at 2ms^-2 ?

Find force required in accelerating a 3 kg mass at 5 m/s2 and a 4 kg mass at 4 m/s2

In the system shown in the adjoining figure, the acceleration of the 1 kg mass is m//s^(2) . (take g = 10 m//s^(2) )
