• ↋=−dΦ/dt

• F=qE

What is the direction of the electric field for a positive charge?

• Toward the charge

• Away from the charge

• Perpendicular to the charge

• Circular around the charge

What is the S.I. unit of electric field?

What is the relationship between electric force and electric field?

• F=qE

• E=mc2

• F=k⋅(q1⋅q2)/r2

What is electric potential?The energy a charged object has due to its position

• The energy a charged object has due to its position

• The rate of flow of electric charge

• The work done to move a charge from one point to another

• The force experienced by a unit charge in an electric field

How is electric potential related to the electric field?

• Electric potential is the gradient of the electric field

• Electric potential is the product of electric field and distance

• Electric potential is inversely proportional to the electric field

• Electric potential and electric field are independent of each other
