The tension on a rope causing the box to accelerate is 30 N.
Tension on the rope
The tension experienced by the rope pulling the mass at the given acceleration is determined by applying Newton's second law of motion as shown below;
T = ma
where;
- m is the mass of the object
- a is the acceleration of the object
T = 7.5 x 4
T = 30 N
Thus, the tension on a rope causing the box to accelerate is 30 N.
