dy Notes O Ask Your Teacher 2. -12 points CJ10 19.P.002 A particle with a charge of -1.1 uC and a mass of 2.3 x 10-6 kg is released from rest at point A and accelerates toward point B, arriving there with a speed of 37 m/s. The only force acting on the particle is the electric force. (a) Which point is at the higher potential? O point A o point B Give your reasoning. O Negative charge accelerates from a lower potential to a higher potential O Negative charge accelerates from a higher potential to a lower potential. (b) What is the potential difference Vs - VA between A and B?

During this time, 1400 C of charge passes through the battery pack. Find the minimum horsepower rating of the car. hp Additional Materials Section 19.2Explanation / Answer
2.
a)
Point B is at higher potential.
=====
b) negative charge accelerate from lower to higher potential.
=====
c) using conservation of energy
qV= 0.5mv^2
1.1*0^-6* V= 0.5*2.3*10^-6* 37^2
V= 1431.22 V
======
