  • Question 2/10
    4 / -1
    In the following diagram, the work done in moving a point charge from point P to point A, B and C is respectively as WA , WB and WC , then

    Solutions

  • Question 3/10
    4 / -1
    A positively charged ball hangs from a silk thread. We put a positive test charge q0 at a point and measure F/q0, then it can be predicted that the electric field strength E will be
  • Question 4/10
    4 / -1
    The positive terminal of 12 V battery is connected to the ground. Then the negative terminal will be at
  • Question 5/10
    4 / -1
    A charge (–q) and another charge (+Q) are kept at two points A and B respectively. Keeping the charge (+Q) fixed at B, the charge (–q) at A is moved to another point C such that ABC forms an equilateral triangle of side l. The net work done in moving the charge (–q) is
