Question

(i) A force of 15 N moves a body with an acceleration of 3 ms ?
Its mass will be:
A. 10kg
B. 8kg
C. 12kg
D. 5kg​

Answer 1

Answer:

F=ma

15=m×3

m=5

mass is equal to 5kg

Answer 2

Answer:

Answer:

Here,

F (force) → 15 N

a ( acceleration) →\bold{ 3m{s}^{-2}}3ms

−2

To find :—

† m (mass)

\bold{ We \: \: know \: \: that,}Weknowthat,

\bold{ \color{blue}{f \: = \: ma}}f=ma

Substituting the values,

→ \: \bold{15 = m \: \times 3}→15=m×3

→ \bold{\: m \: = \frac{15}{3} }→m=

3

15

→ \large{ \mathtt{ \color{red}{\bold{ \: m \: = 5 \: kg}}}}→m=5kg

Answer:— (D)5kg
