(Solved): 1) 10 microcoulomb charge is placed at x=0y=0 and -10 microcoulomb charge is placed at x=8 and y=0. ...
1) 10 microcoulomb charge is placed at and -10 microcoulomb charge is placed at and . Calculate voltage at and . Draw approximately 5 equipotential lines and 5 electic field line. 2) In Ohm's Law experiment voltage and current is measured and given at a table as Draw the V vs I graph and obtain the slope. What does this slope value correspond to.
Expert Answer
Integrating the electric field along a path from a reference point to the place of interest is required to determine the voltage at the given point. Since the electric field is a vector, we must consider both its magnitude and its direction.We know that the electric field of a point charge is given by: E is the electric field, k is the Coulomb constant , q is the charge, and r is the distance between the point charge and the point of interest.First, let's calculate the electric field at the point (4,3) due to the charge at the origin:
