\f4. Calculate the magnitude and direction of the electric field at point Z in Figure 13, due to the charged spheres at points X and Y. +50.0 JC -10.0 uC 0.45 m 0.30 m X Y Z Figure 13 5. Determine the magnitude and direction of the electric field at point Z in Figure 14, due to the charges at points X and Y. 6. The electric field strength midway between a pair of oppositely charged parallel plates is 3.0 x 103 N/C. Find the magnitude of the electric field midway between this point and the positively charged plate. 7. In the parallel plate apparatus in question 6, what would the electric field strength become if half of the charge were removed from each plate and the separation of the plates were changed from 12 mm to 8 mm?1. A negative charge of 2.4 X 10 C experiences an electric force of magnitude 3.2 N, acting to the left. (a) Calculate the magnitude and direction of the electric field at that point. (b) Calculate the value of the field at that point if a charge of 4.8 x 10- C replaces the charge of 2.4 X 10-6 C. 2. At a certain point Pin an electric field, the magnitude of the electric field is 12 N/C. Calculate the magnitude of the electric force that would be exerted on a point charge of 2.5 x 10-7 C, located at P. 3. Calculate the magnitude and direction of the electric field at a point 3.0 m to the right of a positive point charge of 5.4 X 10-4 C
