Force = massx acceleration

F = 2.5 kg x g .........g=9.81 m/sec^2.
.
.F=24.5 N...................N=Newton.

To find the weight in Newtons, multiply the mass by the acceleration due to gravity:

2.5 kg * 9.8 m/s^2 = 24.5 N

"weight" is normally expressed in kg. The force of object A on earth due to gravity would be 24.5 N.
