A circular parallel-plate capacitor whose plates have a radius of 25 cm is being charged with a current of 1.3 A. What is the magnetic field 11 cm from the center of the plates

The given circular parallel-plate capacitor has a magnetic field at 11 cm from the center of the plates as 2.364 x 10⁻⁷ T.

Given;

radius of the circular plate, d = 25 cm = 0.25 m

current in the plate, I = 1.3 A

distance from the center of the circular plate, r = 11 cm = 0.11 m

To find:

magnetic field (B)

The magnetic field from the given distance is calculated as from Biot Savart equation:

Therefore, the magnetic field 11 cm from the center of the plates is 2.364 x 10⁻⁷ T.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
