The correct answer would be it would decrease.
P.S. If you need any technical support with Windows 10, just send a message to me on Brainly and I'll try to figure it out.
Answer:
Explanation:
Let the tension in the string be T . At the top of the circle , total force acting on them = T + mg . This will provide centripetal force
T + mg = m v² / r
4 + .25 x 9.8 = .25 x v² / .62
6.45 = .25 v² / .62
v² = 16
v = 4 m /s .
