Question 29 Consider a solid conducting sphere with radius R. as shown in the image below. The electric field on the surface of the conducting sphere is E. What is the electric field at a distance of 4R from the center of the sphere? OE/B OE O None of the given choices 2 pts O E/16 of
Question 30 The figure below shows two oppositely charged conducting plates with an equal magnitude of surface charge densities + anda. At point r above the surface of the conducting plate with surface charge density+o, the electric field -O +o 2 pts Opoints downward toward the surface of the conducting plate with surface charge density. O is equal to zero. Opoints towards the left, parallel to the surface of the conducting plate with surface charge density + O None of the given choices O points upward away from the surface of the conducting plate with surface charge density +
