Question
Part A is true or false.
Potential Field Part A , and Q3. The values of the potentials are in kV as indicated for the +5, 0, and -5 kV contours. The positions of the The lines show the equipotential contours in the plane of three point charges, Q charges are indicated by the dots. Q1 o2 Qa em 1 The letters are on the equipotential contours. The force on a proton at g points to the bottom of the page. Charge Q2 is the largest negative charge. The electric field at k is zero. Q1 is a negative charge. The electric field at i is stronger than at j. Charge Q3 has the largest magnitude of all. Submit Answer Tries 0/15Explanation / Answer
Q3 is positive, Q2 is negative, and field poitns from positve to negative, hence force on a positive(proton) charge poitns upwards false.
True, field lines are closely saced near q2, and potential is negative, so yes it is largest negative.
K lies on contour with zero potential ,so TRUE.
potential given is -5kV, so yes Q1 is negtive.True.
electric field is given by {-dv/dr}
{-(Vj -Vi)/rj-ri} => Clearly Vj is less than Vi so Field lines point outward from i and towards j, so field is more at i, than at j.TRUE.
Field lines are farthest from Q3, so it has least magnitude.FALSE.
