Answer:
4. 24 N
5. 62.25 N
6. 16.6 N
Explanation:
For 4 No.
Mass (m) = 6 kg
Acceleration (a) = 4 m/s(square)
Now,
According to the formula,
F = ma
= 6 x 4
= 24 kg m/s(square) or N
5 No. is also same as 4 no. as both the values of acceleration and mass is given in SI units.
But, In No. 6, Mass is given 2000 g. So, First change the gram (g) into kilogram (kg). For that, divide it by 1000. You will get the value of mass as 2 kg.
And same formula (F = ma) is applied on it.
Put "m" as 2 and "a" as 8.3 and you will get the answer as 16.6 kg m/s(square).
That is the whole process. For no. 5, You just need to put the value of "m" and "a" and multiply them. You will get the answer as 62.25 N.
Note: N means Newton which is the SI unit of Force.
Hope you get it.
