Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points Consider three charges arranged as shown. − + + 4 . 1 cm 2 . 7 cm 3 . 4 μ C 6 . 5 μ C − 2 . 2 μ C What is the magnitude of the electric field strength at a point 2 . 9 cm to the left of the middle charge? The value of the Coulomb constant is 8 . 98755 × 10 9 N · m 2 / C 2 . Correct answer: 3 . 75658 × 10 8 N / C. Explanation: Let : q 1 = 6 . 5 μ C = 6 . 5 × 10- 6 C , q 2 = 3 . 4 μ C = 3 . 4 × 10- 6 C , q 3 = − 2 . 2 μ C = − 2 . 2 × 10- 6 C , r 1 , 2 = 4 . 1 cm = 0 . 041 m , r 2 , 3 = 2 . 7 cm = 0 . 027 m , x = 2 . 9 cm = 0 . 029 m , and k e = 8 . 98755 × 10 9 N · m 2 / C 2 . r 1 = r 1 , 2 − x = 0 . 041 m − . 029 m = 0 . 012 m r 2 = x = 0 . 029 m r 3 = r 2 , 3 + x = 0 . 027 m + 0 . 029 m = 0 . 056 m vector E net = vector E...
