boy is whirling a stone around his head by means of a string. The string makes one complete revolution every second; and the tension in the string is FT. The boy then speeds up the stone, keeping the radius of the circle unchanged, so that the string makes two complete revolutions every second. What happens to the tension in the sting? * aThe tension reduces to half of its original value. b. the tension is unchanged.
