    Answer:

    if 2 forces of 10 Newton and 15 Newton act in the same direction then the resultant force should be vector sum of the two forces

    or, resultant is = (10 +15) N = 25N

    If you apply the both the forces in same direction the net resultant forces will lead the body to accelerate ;lets say the body have mass *m*

    so it will have and acceleration by the formula f=ma

    net force=10+15=25

    f=ma

    25=ma

    a=25/m

    and if the net forces are on opposite direction then

    f=15-10 (since the higher magnitude will produce the acceleration)

    so f=5

    5=ma

    a=5/m

    and if the both forces acts on the top part of the mass it will be balanced by the normal reaction force

    15+10+mg=N (mg also acting downwards)

    if one force is up and one is down so it will be

    15-10+mg=N
