Does electric field depend on the magnitude of the test charge?

The strength of the electric field depends on the source charge, not on the test charge. Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field.

Is electric field is independent of magnitude of source charge?

The electric field is defined as the force per unit test charge. It certainly depends on the magnitude, location and distribution of the source charge(s).

What happens to the electric field when the magnitude of the charge increase?

Electric field lines point away from positive charges (like charges repel) and towards negative charges (unlike charges attract). Field lines do not touch or cross each other. Field lines are drawn perpendicular to a charge or charged surface. The greater the magnitude of the charge, the stronger its electric field.

Why must the magnitude of the test charge be very small?

We use a test charge of small magnitude so that it does not disturb the distribution of the charges whose electric field we wants to measure otherwise the measured field will be different from the actual field.

What electric field depends on?

The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.

What is the magnitude of electric field at the position of this charge?

, where E is the electric field and q is the charge. The magnitude of the electric field at the position of this charge is 1.17 × 106 N/C.

What is the magnitude of charge on an electron?

The charge of the electron is equivalent to the magnitude of the elementary charge (e) but bearing a negative sign. Since the value of the elementary charge is roughly 1.602 x 10-19 coulombs (C), then the charge of the electron is -1.602 x 10-19 C.

Does electric field E due to the source charge q depend upon test charge q?

The electric field is thus seen to depend only on the charge Q and the distance r; it is completely independent of the test charge q.
