Untitled College Physics IIExam 2: GAIA’s insightEPCC ANSWER ESSAY QUESTIONS WITHIN 3 SENTENCES. NO EXCEPTIONS. 1. Refer to figure 1. Three charged particles are configured in a triangular configuration. The red highlighted positive charges are anchored. The free-floating charge (q3) of mass 100.0 kg is initially motionless. Calculate force the free-floating charge experiences and the work done on it after 5.12 s elapses. 2. Explain how electric potential is different from electric potential energy. 3. What is the electric flux of a system where a uniform electric field of 1200.0 N/C passes through a Gaussian surface in the shape of a rectangle that is 0.20 m by 0.40 m, tilted at 60.0°. 4. Refer to figure 2. A positively charged block is held stationary atop a ramp by an anchored charged ball at the end of a frictionless ramp. Calculate the mass of the block. 5. Refer to figure 3. A dipole is immersed in an 2.40x105 N/C electric field. Calculate the maximum torque it experiences and determine if it rotates counter-clockwise or clockwise.

Use your own sketches to help illustrate your response if needed. Refer to figure 1 for the following problems. 1. Calculate the flux of electric field lines emanating from a line charge passing through a rectangular surface (2.00m by 2.50m) which is perpendicular to the field lines. 2. Calculate the flux if the rectangular surface is parallel to the field lines. 3. Calculate the flux if the rectangular surface is at 60.0° to the field lines.
