two forces of 10n and 15n are acting simultaneously on an object in the same direction. the resultant is?

1. 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=[tex]10+15=25[/tex]

   f=ma

   [tex]25[/tex]=ma

   a=[tex]25/m[/tex]

   and if the net forces are on opposite direction then

   [tex]f=15–10[/tex] (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

   [tex]15–10[/tex]+mg=N
