Graphically, the effect of multiplying a vector p\mathbf p by the scalar 0.50.5 is that (a) ∣p∣|\mathbf p| is doubled while its direction remains unchanged. (b) ∣p∣|\mathbf p| is halved and its direction is reversed. (c) ∣p∣|\mathbf p| is halved while its direction remains unchanged. (d) ∣p∣|\mathbf p| remains unchanged but its direction is reversed.
