Apoint charge of -2.15uc is located in the center of a spherical cavity of radius 6.51cm inside an insulating spherical charged solid. the charge density in the solid is 7.36*10^-4c/m3 .

1.calculate the magnitude of the electric field inside the solid at a distance of 9.50cm from the center of the cavity.

express your answer using two significant figures.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
