Question

Matt forgot to put the fabric softener in the wash. As his socks tumbled in the dryer, they became charged. If a small piece of lint with a charge of +1.25 E -19 C is attracted to the socks by a force of 3.0 E -9 N, what is the magnitude of the electric field at this location?

3.8 E10 N/C

4.2 E10 N/C

2.4 E10 N/C

1.5 E10 N/C

    Answer: 2.4*10‐²⁴ N/C

    Explanation:

    Electric field intensity is the force acted per unit charge on a given surface

    E = F/Q

    Data

    F = 3.0*10‐¹⁹ N

    Q = 1.25 * 10-¹⁹ C

    E = 3.0 * 10-⁹ / 1.25*10-¹⁹

    E = 2.4*10¹⁰ N/C
