Answer:
Given: Number of Forces are acting on a stationary object. A Stationary Object is an object which is at rest with respect to it's surroundings.
Now, the given conditions and the state in which they will be true :
1. does not accelerate- This means that the body doesn't show change in it's velocity with time. This can only happen when all the forces acting on the body are constant. It means neither do they change their magnitude, nor the direction. When all the active forces are constant, the body will stay at rest or either move with same velocity. Hence, there would be no change in acceleration.
2. does not rotate- This means that the body doesn't possess Rotational Motion. This can only happen if there are no couple forces acting on the body. If there are balanced forces at the two ends of the body, they'll act as a couple, and will rotate the body. The given condition can only happen when there are unbalanced forces at both ends of the body.
