Task 30874.
The circular conductive loop is in a uniform magnetic field, the induction of which varies in time according to B = 5 * 10 ^ -3 * t ^ 2 T. loop radius of 2 cm. Loop resistance 10 Ohm. The angle between the direction vector and the plane of the contour in 30 °. Find: 1) charge last on the circuit during the time interval from 2 to 4; 2) the current point in the loop 4c in time.
Detailed solution with a short recording conditions, laws and formulas used in the decision, the withdrawal of the calculation formula and the answer.
If you have any questions about the decision to write. I try to help.
