1)1. Two charged point bodies are placed into the opposite on diagonal vertices of a rectangular with sides of 6 and 8 cm in vacuum – Q1=3.2x10-11 C; Q2=-4.267x10-11 C. Calculate the electric field intensity at two other vertices of the rectangular and the point of its diagonals crossing
2)7. A straight conductor of length l=80cm with current I=20A is placed into a uniform magnetic field with magnetic flux density B=1.2T . Calculate the force influencing the conductor of the mutual displacement between current direction and density is α=30o; α=60o; α=90o.
3)8. The coil with L=30mH is supplied with DC voltage of 50V. Calculate resistance of the coil if at the moment when current achieves the value of 10 A the speed of its increasing is 1000A/s
