Question

Find the locus of a point whiich moves in such a way that the sum of its distances from the points `(a, 0, 0) and (a, 0, 0)` is constant.
A. Circle
B. Ellipse
C. Hyperbola
D. Parabola

Answer 1

Correct Answer - C
When a point P moves such that the difference of its distances form two given points (c, 0) and (-c, 0) is constant, then the locus of the point P is hyperbola.
It is the definition of hyperbola also.
