An electron that is released from the rest in a uniform electric field of 30 N/C experiences a voltage change of 60 volts as the electron moves ____ m in the field.
a. 5
b. 2
c. 3
d. 0
e. 10
f. 0.4
g. 30
To answer this question, we need to use the equation that relates the voltage change to the electric field strength and the distance traveled by the electron.
The equation is:
Voltage change (ΔV) = Electric field strength (E) × Distance traveled (d)
We are given that the electric field strength is 30 N/C and the voltage change is 60 volts. We need to calculate the distance traveled by the electron (d).
Rearranging the equation, we can solve for d:
d = ΔV / E
Substituting the given values:
d = 60 volts / 30 N/C
d = 2 meters
Therefore, the electron moves 2 meters in the field. The correct answer is option (b) 2.
