Front

What is an electric field?

Back

The space around an electric charge that causes other charges to experience a force, either attracting or repelling them.

Front

When an object loses electrons, it becomes __________.

Back

Positively charged.

Front

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

Back

Away from the charge.

Back

Towards the charge.

Front

What is the unit of electric field strength?

Back

Newtons per Coulomb (N/C).

Front

How do you calculate the electric field (E) created by a point charge (Q) at a distance (r)?

Back

E = k * |Q| / r², where k is Coulomb's constant.
