Answer:
Zero
Explanation:
Two long parallel wires each carry the same current I in the same direction. The magnetic field in wire 1 is given by :
Magnetic force acting in wire 2 due to 1 is given by :
Similarly, force acting in wire 1 is given by :
According to third law of motion, the force acting in wire 1 will be in opposite direction to wire 2 as :
So, the total magnetic field at the point P midway between the wires is in what direction will be zero as the the direction of forces are in opposite direction.
Answer: I don't do adopt me but I do have a Ro.blox username its Nvm i cant but my user name
Explanation:
D is definitely the correct choice here.
I think a case could also be made for choice-B, but that would be a tough, complex operation.
Answer:
I think it should be D
Explanation:
This is because the arrow pointing right is bigger than the arrow pointing left. Hence we can conclude the the force acting on the right is greater and hence it is accelerating
I know that in order for a hurricane to gain energy, it needs water and warm air and since hurricanes form in the water due to thunder storms near Africa, it loses energy because there is not much water on land than it is in the ocean or sea. :)
