9. Electric field is a _______ a) Scalar quantity b) Vector quantity c) Tensor quantity d) Quantity that has properties of both scalar and vector
Answer: b Explanation: A scalar quantity is a quantity with magnitude only but no direction. But a vector quantity possesses both magnitude and direction. An electric field has a very specific direction (away from a positive charge or towards a negative charge). Hence electric field is a vector quantity. Moreover, we have to use a vector addition for adding two electric fields.
