PRACTICE FINAL EXAM SOLUTIONS – IUPUI Physics 219 1) Consider the two point charges shown in the figure. (A) Calculate the net electric field at x = 4.0 m. E net = 5.394 N/C (B) Determine the direction of the net field. θ = 233.13° y E 1 = 8.99 N/C at 0° 3.0 m +20 nC E 2 = 7.192 N/C at –36.87° E 1 0 | –16 nC x E 2 2) A proton is accelerated from rest by a uniform electric field of magnitude 2.00×10 4 V/m. After the proton travels 3.00 mm, calculate (A) the potential difference through which it travels. 60 V (B) the kinetic energy (in electron-volts) of the proton. 60 eV (C) its final speed. 1.07 × 10 5 m/s 3) A copper of length 75 cm and diameter 2.5 mm has a potential difference of 9.0 V between its two ends. The resistivity of copper is 1.70×10 –8 Ω-m. (A) What is its resistance? 2.6 × 10 –3 Ω (B) How much power is dissipated? 3.12 × 10 4 watts (C) How many kilowatt-hours does it consume for an entire day? (31.2 kW)(24 hrs) = 749 kWh 2.0 Ω 4) In the circuit shown, the current through the 2.0-Ω resistor is 1.5 A. Calculate (A) the total equivalent resistance. 3.0 Ω (B) the battery emf E .
