Question 1 (1 point) What is the surface integral f d.A in m of a sphere of radius (3.47x10*1) cm? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer Question 2 (1 point) Saved The potential difference between two points is 100 V. These points are separated by 0.5 m. If a particle with a charge of 2 C is moved from one of these points to the other, the magnitude of the work done is: O 2J 100 V 100 J O 50 J O 200 J Question 3 (1 point) How does the addition of a dielectric NOT affect a parallel plate capacitor? It decreases the capacitance of the capacitor It stores energy in the dielectric by polarization It usually increases the dielectric strength and increases the breakdown Voltage O It allows more charge to be held on the plates at a given potential It lowers the overall electric field between the charge platesQuestion 4 (1 point) If the electric potential is constant in a region of space, what can you say about the electric field? It must be the same constant It must be decreasing O It must be zero Question 5 (1 point) Calculate the potential in volts at a distance of (4.520x10*0) m from a point charge of (-6.6x10^0) UC, if the point charge is inside a dielectric material with a dielectric constant k = (1.750x10^0) Note: Your answer is assumed to be reduced to the highest power possible.
