a)The figure below shows a test charge
q betweenthetwo positive charges. Find the force (in newtons) on thetestcharge for
q = 2 µC. Give a positive answer iftheforce is to the right and a negative answer if the force is totheleft.
b) For the previous question, find the electric field(innewtons/coulomb) at the position of test charge. Again, supplyapositive value if the electric field points to the right andanegative value if it points to the left.
c) How much work (in joules) is done in moving a charge of 2.5μCadistance of 53 cm along an equipotential at 10~V?
d) The field lines associated with a uniform electric fieldina region of space are shown in the figure below. Imaginedrawingtwo equipotentials in the plane of the figure, one passingthroughpoint A and and one passing through point B. If the electricfieldis 450 N/C, how much does the potential change in going from AtoB? Provide your answer in volts and use a positive value ifitincreases and a negative value if it decreases.
Please help and you will get a lifesaver rating!! Thankssomuch
