Question

Suppose that a = 1.3 cm (see figure).

Part A- Determine the magnitude of the electric field at point 1 in (Figure 1).

Part B -

Determine the direction of the electric field at that point.

To the right.

Part C - Determine the magnitude of the electric field at point 2.

Part D- Determine the direction of the electric field at that point.

To the right.

Upward. Downward. To the left.

To the right.

Part C - Determine the magnitude of the electric field at point 2.

Part D- Determine the direction of the electric field at that point.

Upward. Downward. To the left.

To the right.

Figure 1 of 1 75v 0V

taking the reference point as the center of the 0V circle and

point 1 is on the 50V curve and at a distance of 2.5*a

r = 2.5*1.3 cm = 3.25 cm = 0.0325 m

PartA

from the relation between electric field and potential

V = E*d

E1 = V/d = 50/0.0325 V/m = 1538.462 V/m

Part B

the direction is as the field is +ve so the direction is upward

Part C

at point 2 , which is at a distance of 1.5a units

d = 1.5*1.3 cm = 1.95 cm = 0.0195 m

now the field at point 2 is

E2 = V/d = 50/0.0195 V/m

E2 = 2564.103 V/m

ParD

the direction is as the field is +ve so the direction is downward
