Answer:
I would say a but it could be b too. It’s definetly not the last two.
I say a because no reason to go up the hill and that’s not gonna give her speed going down so. Good luck!
Explanation:
Answer:
The force will be doubled.
Explanation:
Just looking at the situation,
<em>We are supposing the distance in between these charges is the same in both the cases which is r</em>, so for the first normal case,
, q1, q2 are the two charges and r is the distance between them.
Now take the other case when the the Charges are doubled,
you can see clearly from the above equation that the new force which is has been doubled.
I hope it helps,
Thank you.
The best conclusion that can be drawn is that D) A current does not flow in the wire
If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.
If the angle is 45, then there is still some work involved.
The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.
