5.Consider the electric field pattern around two positive charges. as shown. If you put an electron at point B. which way will it accelerate? 8. Consider a current loop (only top wire shown in figure below) in a uniform magnetic field (pointing to right). Which direction is the angular acceleration? A) out of the page B) into the page C) parallel to magnetic field . D) parallel to wireE) none of the above

Explanation / Answer

electron accelerattes in opposite to direction of a non uniform electric field . so, the direction (D) represents the correct direction of acceleration of the electron.

By using the right hand rule, the torque (t bar=A bar cross B bar) acting on the loop into the page. So, the angular acceleration of the loop is along the direction of the magnetic field (use right hand rule, t bar=rbar cross F bar).
