Explain why a charged balloon is repelled by another charged balloon whereas an uncharged balloon is attracted by another charged balloon?

Explain why, a charged balloon is repelled by another charged balloon whereas an uncharged balloon is attaracted by a charged balloon.

Helium Balloon Challenge

If r is the radius of spherical balloon at time t and the surface area of balloon changes at a constant rate K, then . . ..

A balloon reses from rest on the ground with constant acceleration g // 8. A stone is dropped from the balloon when the balloon has resen to a height of (H). Find the time taken by the stone to reach the ground.

A rubber balloon is given a charge. Q distributed uniformly over its surface. Is the field inside the balloon zero everywhere if the balloon does not have a spherical surface?

A balloon is rising vertically upwards. An an instant, an observation on the ground, whose distance from the balloon is 100 meters, sees the balloon at an angle of elevation of 30^(@) . If the balloon rises further vertically to a point where the angle of elevation as seen by the observer is 45^(@) , then its height (in meters) from the ground is ("Take "sqrt3=1.73)

The air if filled in a balloon and the volume of balloon increases gradually. Find the rate of increase of volume of balloon with radius when of balloon becomes 30 cm.
