Here is two statement regarding scalar and vector quantities. "Statement-A" Scalar Quantities: A physical quantity which is described completely by its magnitude is called a scalar quantity. It has only magnitude and no direction. Length, distance, area, volume, mass, time and energy are the examples of scalar quantities. "Statement-B" Vector Quantity: A physical quantity which is described completely by its magnitude as well as direcion is called a vector quantity. it has both magnitude and direcion. Displacement, velocity, acceleration, force and weight are examples of vector quantities. Which of the following statement is wrong
