Questions and Answers

What is the formula for electric field intensity?

E = F/m

E = F/q (correct)

E = F/v

E = F/a

What is electric field intensity and how is it calculated?

Electric field intensity is the magnitude and direction of the electrostatic force experienced by a unit positive point charge. It is calculated using the formula E = F/q, where F is the force experienced by the test charge and q is the test charge.

What is the unit for electric field intensity?

Coulomb

Volt

Joule

Newton/Coulomb (correct)

Why should the test charge be small when measuring electric field intensity?

The test charge should be small to avoid affecting the charge distribution on the source charges. Signup and view all the answers

What is the direction of the electric field?

Away from a positive charge Signup and view all the answers

Study Notes

Electric field is the region around a charged particle or body where another charge will experience electrostatic force.
Electric field intensity is the magnitude and direction of the electrostatic force experienced by a unit positive point charge.
The formula for electric field intensity is E = F/q, where F is the force experienced by the test charge and q is the test charge.
The test charge should be small to avoid affecting the charge distribution on the source charges.
Electric field intensity is a vector quantity with the same direction as the force experienced by a positive charge.
The direction of the electric field is always away from a positive charge and towards a negative charge.
The unit for electric field intensity is Newton/Coulomb.
The dimensional formula for electric field intensity is [MLT^-3A^-1].
Electric force on a charge q in an electric field with intensity E is given by F = qE.
The electric field intensity in a downward direction will result in an electric force in the same direction.
