Question 1 (1 Q3 Q1 What is the electric potential at the dot in the figure? The charge on Q1 is 9.00 nC, the charge on Qz is 7.00 nC and the charge on Q3 is 9.00 nC. The distance between charge O, and charge zis 7.00 cm. The distance betweern Q2and is 2.00 cm. 2.02x103 v 5.20×103 V 4.91 103v 6.07x103v Question 2 An electric potential of 3.78x1032v(where x is measured in cm) is acting along the x-axis. A particle with a charge of 9.40 nC and a mass of 6.90 g moves in this electric potential with turning points of+6.60 cm. What is the particle's maximum speed through the electric potential? 0.670 m/'s -0.430 m/s 1.77 m/s 0.335 m/s

Explanation / Answer

1. V = k q / r

so V = [(9 x 10^9 x 9 x 10^-9)/0.02] + [(9 x 10^9 x 7 x 10^-9)/sqrt(0.02^2 + 0.07^2)] + [(9 x 10^9 x 9 x 10^-9)/0.07]

V = 6072.5 Volt
