Aping-pong ball is held submerged in a bucket of water by a string attached to the bucket's bottom. salt is now added to the water in the bucket, increasing the density of the liquid. what happens to the tension in the string ? the tension does not change. the tension increases. the tension decreases. what happens to the tension in the string if the ping-pong ball is replaced by a smaller spherical object of equal weight? what happens to the tension in the string if the ping-pong ball is replaced by a smaller spherical object of equal weight? the tension does not change. the tension increases. the tension decreases. salt is now added to the water in the bucket, increasing the density of the liquid. what happens to the tension in the string ?
