Solve for the following word problem. Show all necessary solution. Final answer should be rounded off to the nearest two decimal place. 1. What is the magnitude of a point charge that produce an electric field of 75N/C at 1.50m away from the charge? 2. Compute for the magnitude of the electric field at 140cm from an 8nC charge. 3. A force of 0.15N is directed to the west of a .75uC point charge. Compute for the magnitude and direction of the electric field. 4. A 15nC charge were place 175cm to the right of an 8nC charge. Compute for the electric field at the middle of those two charges. Supposed the 8nC charge is located at the origin and both charges lie on the x-axis. Compute for the distance from the origin where there is no electric field can be experience. 5. Two-point charges were place at a cartesian coordinate system with the following coordinates q1 (-3, 4) and q2 (2, -2). Compute for the magnitude and direction of electric field at the origin if q1 = .275 C and q2 = .010uC. Supposed 1 unit in the cartesian plane is equal to 1 m. 6. Three charges are in the corner of an equilateral triangle whose side is equal to 250cm. Compute for electric field at P. Supposed P is located at the middle of q2 and q3. If a 1.50C charge Q1 were placed at P, compute for the net force at P. Q2 03
