Question

A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw based on this description?
A.The electric field points to the left because the force on a negative charge is opposite to the direction of the field.
B. The electric field points to the right because the force on a negative charge is in the same direction as the field.
C. No conclusion can be drawn because the sign of the charge creating the field is unknown.
D. No conclusion can be drawn because the amount of charge on the test charge is unknown.

2 Answer

  • Answer:

    A.The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

    Explanation:

    As we know that electrostatic force on a charge in external electric field is given as

    [tex]\vec F = q\vec E[/tex]

    so here the force and electric field will be in same direction if charge is positive and if the charge is negative then force will be in opposite direction to the electric field.

    So we know that since the electron is negatively charged so the force on electron must be opposite to the electric field present in that region.

    So correct answer will be

    A.The electric field points to the left because the force on a negative charge is opposite to the direction of the field.

  • We have that for the Question "A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw based on this description?" it can be said that

    The best conclusion to draw based on this description is

    • The electric field points to the right because the force on a negative charge is in the same direction as the field.

    Option B

    From the question we are told

    A negative test charge experiences a force to the right as a result of an electric field. Which is the best conclusion to draw based on this description?

    Electric field

    The electricity of an electric powered area E at any factor might also be described as the electric, or Coulomb, pressure F exerted per unit high-quality electric powered cost q at that point, or truely E = F/q.

    Therefore

    The best conclusion to draw based on this description is

    • The electric field points to the right because the force on a negative charge is in the same direction as the field.

    Option B
