Question

Force required in accelerating 4 kg mass at 6 m / s² and a 5 kg at 5 m /s², will be
Zero in both the cases
Same in both the cases
Greater for 4 kg mass at 6 m/s²
Greater for 5 kg mass at 5 m /s²​

Answer 1

Answer:

Force F=ma

(1) : F

1

=m

=2×5=10 N

(2) : F

=4×2=8 N

So, 2 kg will require greater force.
