Question

(X)If F= 4N, a=2m/s2 then ma
*2 kg
*4 kg
*6 kg
*8 kg​

Answer 1

Answer:-

• Force=4N
• Acceleration=2m/s$^2$
• Mass=?

We know that

$\boxed{\sf Force=Mass\times Acceleration}$

$\\ \qquad\quad\sf\longmapsto Mass=Force\times Acceleration$

$\\ \qquad\quad\sf\longmapsto Mass=4\times 2$

$\\ \qquad\quad\sf\longmapsto Mass=8kg$

Hence option d is correct.

Answer 2

Answer:

(A)The mass of the body is 2kg

Explanation:

The proper question is-"If F= 4N, $a=2ms^{-2}$ then the value of m is?"

Force and acceleration are given we are required to find the mass of the system.

According to newtons`s second law of motion,The force produced by a body is the product of its mass and acceleration.Hence we write it mathematically as

$F=ma$

Substituting the value of force and acceleration in the above relation,we get

$4=m\times2= > m=2kg$

Therefore,the mass of the body is 2kg
