The force of a charge in an electric field is:
In this case we know the electric field is:
and that the charge is that of the electron, then we have:
Therefore, the magnitude of the force is
and in points down.
The weight of the electron is:
Making the quotient between the force we have:
Therefore, the electric force is approximately 1e9 times the weight.
The voltage in the resistor is 63 V
Explanation:
We can solve the problem by applying Ohm's law, which states the relationship between voltage, current and resistance in a resistor:
where
V is the voltage
R is the resistance
I is the current
For the resistor in this problem, we have:
I = 0.42 A is the current
is the resistance
Substituting into the equation, we find the voltage needed:

Answer:
Total distance she cover = 14km
Magnitude of displacement = 10 km
Direction of her displacement is East-south
Explanation:
Given:
Distance travel (East) = 3 km
Distance travel to south = 8 km
Distance travel (East) = 3 km
Computation:
Total distance she cover = 3km+8km+3km
Total distance she cover = 14km
Magnitude of displacement =
Magnitude of displacement = 10 km
Direction of her displacement is East-south
