- ME. 2. A positive point charge q = 3μC is surrounded by a sphere with radius 0.2m centered on the charge. Find the electric flux through the sphere due to this charge. Select one: O a. 300000 Nm2/C b. 340000 Nm2/C O c. 430000 Nm2/C O d. 400000 Nm2/C Clear my choicearrow_forwardTwo parallel plates are positioned 5.00 cm apart with 3.00 x104 volts across them. The positive plate is at x = -2.50 cm and the negative plate is at x = +2.50 cm. (Assume negative is to the left and positive is to the right.) A point charge of 2.50 x106 C and 2.61 x10 14 kg is released from rest at x = 0.00 m. The electric potential where the point charge is released from is V. The point charge will be accelerated to the (left/right) When the point charge reaches the plate, it will have a kinetic energy of J, or eV. This means the point charge will be traveling at m-s1 when it hits the plate.arrow_forwardGiven that the expression for the current density (See figure below).
