Question

Which of the following statement is INCORRECT regarding the comparison between biot-savart law for the magnetic field and coulomb's law for the electrostatic field?

A Both are long range, since both depend inversely on the square of distance from the source to the point of interest. Correct Answer Incorrect Answer
B The electrostatic field is produced by a scalar source, namely, the electric charge. The magnetic field is produced by a vector source. Correct Answer Incorrect Answer
C There is no angle dependence in biot-savart law which is present in the electrostatic case. The magnetic field at any point is zero Correct Answer Incorrect Answer
D The electrostatic field is along displacement vector joining the source and the field point. The magnetic field is perpendicular to the plane containing the displacement vector and current element. Correct Answer Incorrect Answer

Solution

The correct answer is C
