Answer:
Explanation:
Given that,
The instantaneous current in the circuit is giveen by :
We need to find the rms value of the current.
The general equation of current is given by :
It means,
We know that,
So, the rms value of current is 2.12 A.

Answer:
B. to the right
Explanation:
Given:
- test charge +q
- distance of the test charge from +Q, r
- distance of test charge from +2Q, 2r
<u>Force on the test charge due to +Q:</u>
<u>Force on the test charge due to +Q:</u>
Since all the charges are positive here, so they will try to repel the test charge away. And the force due to charge +Q will be greater so initially the test charge will move rightwards away from the +Q charge.
