What is Grade 12 Physics 2: 3rd Quarter Exam about?
1) A particle with a charge of +8nC moves to the left in a uniform electric field. After moving 3cm, its kinetic energy was measured to be 5x10-4 J. The work done by the electric force was -2.4x10-4 J. The electric potential of the starting point with respect to the endpoint was -0.3 V. The magnitude of the electric field was 8x103 N/C. 2) In a television, electrons are accelerated from rest through a 25000 V potential difference and strike the screen. The electron speed just before striking the screen is
