What is the current through a wire if 240 coulombs of charge pass through the wire in 2.0 minutes?
2 answers:
Answer : Current flowing, I = 2 Ampere
Explanation :
It is given that,
Charge passing through a wire, q = 240 coulombs
Time taken to pass the charge, t = 2 minutes = 120 seconds
Electric current is defined as the ratio of the electric charge divided by time taken to pass the charge.
Mathematically, it can be written as :
Putting the value of q and t we get:
I = 2 Ampere
So, the current passing through the wire is 2 Amps.
Hence, this is the required solution.

Answer:
Explanation:
Force between two charges is given by the following expression
F = Q₁ and Q₂ are two charges and d is distance between two.
.1 =
If Q₁ becomes three times , force will become 3 times . Hence force becomes .3 N in the first case.
Force F = .3 N
If charge becomes one fourth , force also becomes one fourth .
F=
= .025 N.
