Question
Distance of the point $(\alpha ,\beta ,\gamma )$ from Y-axis is
- (a) $\beta$
- (b) $|\beta |$
- (c) $|\beta | + |\gamma |$
- (d) $\sqrt {{\alpha ^2} + {\gamma ^2}}$ ✓ Correct
Three Dimensional Geometry — Class 12 Maths Solution
Step-by-step Solution
Required distance $= \sqrt {{{(\alpha - 0)}^2} + {{(\beta - \beta )}^2} + {{(\gamma - 0)}^2}} = \sqrt {{\alpha ^2} + {\gamma ^2}}$
