Answer:
Two identical closely spaced circular disks form a parallel-plate capacitor. Transferring 2.1×109 electrons from one disk to the other causes the electric field strength between them to be 1.6×105 N/C. What are the diameters of the disks?
Explanation:
Check attachment for solution
Answer:
The magnitude and direction of electric field midway between these two charges is along AB.
Explanation:
Given that,
First charge
second charge
Distance = 20 cm
We need to calculate the electric field
For first charge,
Using formula of electric field
Put the valueinto the formula
Direction of electric field along AB
We need to calculate the electric field
For second charge,
Using formula of electric field
Put the valueinto the formula
Direction of electric field along AO
We need to calculate the net electric field at midpoint
Direction of net electric field along AB
Hence, The magnitude and direction of electric field midway between these two charges is along AB.
Answer:
The answer is B
Explanation:
5/2=2.5
2.5x2=5
Hope this helps ik its kinda confusing lol
Lightning rods provide low resistance paths to the ground that’ll be used to conduct the enormous electrical currents when lightning strikes happen. So the system will attempt to carry the harmful electrical current away from it and safely to ground. The system will have the ability to handle enormous electrical currents associated with the lightning strikes, if they contact a material that isn’t a good conductor then the material will suffer massive heat damage. So the lightning rod system is considered the best conductor & this allows the current to flow to the ground without causing any massive heat damage.
The answer to your question is capacitor :)
