Direction: Please show me (step-by-step) how to find the direction in letter B. As you can see, the questions are already answered. I am currently studying this example in our book. However, I do not know how to find the direction (in letter B). Please teach me how and provide a thorough explanation. I get to study this as I will be having my quiz tomorrow.

5. a. Find the direction and magnitude of an electric field that exerts a 4.80x10-17N westward force on an electron. b. What magnitude and direction of force this field exert on a proton? Solution a: Data: Equation: Substitution: E = ? Fe Fe 4.80x10-17 N E = Fe = 4.80x10-17 N W E = - = 300N/C east 1.6x10-19C q = 1.6x10-19C k = 9x109 Nm2/C2 Solution b: Data: Equation: Substitution: E = 300 N/C east Fe = qoE Fe = qoE = (1.6x10-19C) (300N/C) Fe =? q = 1.6x10-19C Fe = 4. 80x10-17N east
