1. The problem statement, all variables and given/known data Two point-like charges are placed as shown in the figure, r1 = 28.0 cm and r2 = 56.0 cm. Find the magnitude of the electric field at point (p) shown in the figure. Let q1 = −13.0 µC, q2 = +30.0 µC. 2. Relevant equations E1 = k*q1 / r^2 3. The attempt at a solution The electrical field at the two points are the sum of the two electric fields of q1 and q2. E = E1 + E2 The equation for E1 is: E1 = k*q1 / r^2 Plugging in the known quantities: E1 = 8.99x10^9 *13 x10^-6 / 0.28^2 So E1 equals E1 = 1492068.776 N/C The same process goes for E2: E2 = 8.99x10^9 * 30 x10^-6 / 0.56^2 So E2 equals: E2 = 860012.75521 N/C Now adding up E1 and E1 we get: E = (1492.34 + 860.96) x10^3 E = 2350701.531 N/C I am not sure if my reasoning is correct, if anyone can help it'll be much appreciated, thank you!
