PHY137H5 Study Guide - Final Guide: Test Particle, Electric Field
Document Summary
Tutorial 2: problems from previous tests/exams (1) a positive charge +q1 is located to the left of a negative charge q2. On a line passing through the two charges, there are two places where the total potential is zero. The first place is between the charges and is 4. 00 cm to the left of the negative charge. 7. 00 cm (2) a 74. 0-g block carrying a charge q = 35. 0 c is connected to a spring for which k = 78. 0 n/m. The block lies on a frictionless, horizontal surface and is immersed in a uniform electric field of magnitude e = 4. 86 x104 n/c directed as shown in figure. If the block is released from rest when the spring is unstretched (x = 0), using conservation of energy, find the potential difference between its initial position and the point of maximum extension v.
