Question

1.) Select the following which best describes the direction of an electric field.

(a) The electric field points in the direction of higher energy. (b) The electric field points the direction of higher force. (c) The electric field points the direction of the force on a positive charge. (d) The electric field points the direction that any charged object will tend to move if released.

2.) A +2nC point charge is at the point (1cm, 2cm, 3cm). Compute the electric field at a point P at (2cm, 6cm, 2cm).

(a) (2.4 × 103 N/C , 9.4 × 103 N/C , 2.4 × 103 N/C )

(b) (2.4 × 105 N/C , 9.4 × 105 N/C , 2.4 × 105 N/C )

(c) (2.4 × 103 N/C , 9.4 × 103 N/C , 2.4 × 103 N/C )

(d) (2.4 × 105 N/C , 9.4 × 105 N/C , 2.4 × 105 N/C )

(e) (2.4 × 104 N C , 9.4 × 104 N C , 2.4 × 104 N/C )

Explanation / Answer

1)
The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge, therefore the statement which best describes direction of Electric field is
(c) The electric field points the direction of the force on a positive charge.
