Question

Two identical helium filled balloons float in air at a distance d apart along with arrangement .Find magnitude of charge on each balloon when amount of charge on each balloon is same

Answer 1

Given:

The distance is d

To find:

The magnitude of charge on each balloon.

Solution:

The tension along the vertical component is

TcosФ=Mg/2

Horizontal component is

TsinФ=kq²/d²tan²α

Dividing both the equations

tanФ=2kq²/d²Mgtan²α

Therefore the value of q is

q=√(Mgtan²αd²tanФ)/2k
