Question

Finding the electric field from equipo 21,23 a 1 cm X I cm grid is superimposed on a EXAMPLE 21.9 equipotential map of the potential. Estimate the strength and direction of the electric field at points 1, 2, and 3. Show you results graphically by drawing the electric equipotential map. FIGURE 21.23 Equipotential lines. field vectors on th 1 cm 0V 50 V 100 V 1 cm 100 V PREPARE The electric field is perpendicular to the equipoten es, points "downhill," and depends on the spacing between equipotential lines. The potential is highest on the bottom An elevation graph of the potential would look like er-right quarter of a bowl or a football stadium. IStant but unseen source charges have create

Explanation / Answer

the direction of electric filed is upward at point 1.

electric field lines point in the direction of decreasing potential, i.e. they point from high potential to low potential.
