Verified Answer :

Weight of object = mass x acceleration due to gravity
                             =  2.5 x 9.8
                             =   24.5N

Hence option B is correct.
Hope this helps!!

Answer:

The weight of the object is 24.5 Newton.

Explanation:

It is given that,

The mass of an object, m = 2.5 kg

We need to find its weight. We know that the weight of an object can be calculated by the product of mass and acceleration.

W = m g

g is acceleration due to gravity.

\(W=m\times g\)

\(W=2.5\ kg\times 9.8\ m/s^2\)

W = 24.5 Newton

So, the mass of the object is 24.5 Newton. Hence, this is the required solution.
