Answer:
Option c.
Explanation:
Force is a vector quantity. Vector quantity have both direction and magnitude.
Lets suppose right side as positive direction. Then, the force T which is acting on right will become +250 N.
Also, the force S which is acting on left side will become -250 N( due to it acting on opposite direction of force T. ).
For these two forces to be balanced, sum of these two forces must equal to zero.
Now, add these two forces.
250 + ( -250 ) = 0. So, these two forces are balanced. So, option c is correct one.
