charge q1 and q2 are 0.40 m apart. suppose q1 is -5.00 nC and q2 is -2.00 nC. Find the equilibrium for a positive charge placed between them

0.245 m

Explanation:

We are given that

Where

Distance between q1 and q2=0.40 m

We have to find the equilibrium  for a positive charge placed between them.

Let q be the positive charge placed at distance x from q1 .

r1=x

r2=0.40-x

At equilibrium

Total force =0

Where electric force=

By using the formula

By solving we get

It is not possible

Therefore, the equilibrium point for a positive charge placed between them is given by

x=0.245 m

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
