A uniformly charged disk of radius R=35 cm carries a total charge of Q=6μC.
1. Find the magnitude of the electric field E created by the disk at point P located distance of 30 cm from the center of the disk. E= [N/C]
2. What is the direction of the electric field E created by the disk at point P. Direction:
3. Write the expression of the electric field created by the disk at point P. E=<>[N/C]
4. Find the magnitude of the electric field E created by the disk at the point P located at distance of e 6 m from the center of the disk. E= [N/C]
