## 1. Calculate the weight of the electron (electron mass = 9.11x10^-31 Kg)

• 1.08x10^31 N
• Orange N
• 8.94x10^-30 N
• 9.29x10^-32 N
1 of 5

## 2. An electron of charge -1.6x10^-19 C has an electric force of strength 1.4x10^-8 N acting on it. What is the strength of the electric field it is moving through?

• Radish NC^-1
• 2.24x10^-27 NC^-1
• 8.75x10^10 NC^-1
• 1.14x10^-11 NC^-1

## 3. What do these results tell you about how these forces affect the electron?

• The electron would accelerate faster towards the electric field because the force and therefore acceleration is greater (F = ma)
• The strength of the force of gravity is always stronger than the strength of an electric field.
• The electron would keep falling due to gravity even if it was in an electric field.
• The strength of an electric field is always stronger than the force of gravity.

## 4. What is the strength of the electric force that acts on the electron?

• 4.69x10^21 N
• Banana N
• 1.2x10^-16 N
• 2.13x10^-22 N

## 5. How does the force exerted on the electron in the electric field compare to the weight of the electron?

• The force exerted on the electron in the electric field is greater than the weight of the electron.
• The weight of the electron is greater than the force exerted on the electron in the electric field.
• The weight of the electron prevents interference from the electric field.
