Question

In both 1 and 2 electric field is the same everywhere As you move from left to right in each case, the electric field becomes stronger The field in drawing 1 can be created by a single positive charge sitting on the left of the diagram The electric fields in both 1 and 2 could be created by negative charges located somewhere on the right and positive charges somewhere on the left Consider an electron entering a region of constant electric field. Which of the following vectors is always parallel (or anti parallel) to the direction of the electric field Acceleration Displacement Velocity None of the above An electron's path in a certain region in space is shown below. What can you say about the field in that region? The field is that of a point source charge The field is a constant The filed is not a constant It could be any one of the above options Which of the following is true about electric potential? Positive charges move from a region of high potential to low potential Negative charges move from a region of high potential to low potential Both charges move from a region of high potential to low potential Electric potential does not determine the movement of charges Which of the following conclusions CANNOT be drawn based on the statement that "Electrostatic forces are conservative forces"? Total energy is conserved The work done by the force does not depend on the path taken The work done by the force does not depend on the end points of the path taken A potential energy can be defined Consider a parallel plate capacitor. Where is the zero of the potential? That is, which point in space corresponds to V = 0? A point infinitely far away The positive plate The negative plate Doesn't matter since the only physically relevant quantity is Delta V

Explanation / Answer

13) a

since, F = q*E

m*a = q*E

a = q*E/m

14) c

15) a

16) d

17) d
