1. The red dot in the sketch
below represents a charged particle. The green dot represents a
point on an equipotential surface. The blue dot represents a point
on a different equipotential surface. If the potential at the blue
dot is 60 v and the potential at the green dot is 100 v, in which
direction is the E-field at the blue dot?
2. Based on the information given in the question above, what is the sign on the work done by the field when a small positive test charge moves from the blue dot to the green dot?
1. As the electric potential decreases in the direction of electric field and since the potential at green dot is more than that at blue dot, so the electric field direction will be from green to blue dot. And at blue dot it will be radially outward.
2. SIgn of work done will be negative as we are moving against the electric field, so force and displacement are in opposite direction, as force direction is same as that of electric field.
