Assertion : Number of common tangents of
x2 + y2 – 2x – 4y – 95 =0 and x2 + y2 – 6x – 8y + 16 =0 is zero.
Reason : If C1 C2 < |r1 – r2|, then there will be no common tangent. (where C1, C2 are the centre and r1, r2 are radii of circles)
x2 + y2 – 2x – 4y – 95 =0 and x2 + y2 – 6x – 8y + 16 =0 is zero.
Reason : If C1 C2 < |r1 – r2|, then there will be no common tangent. (where C1, C2 are the centre and r1, r2 are radii of circles)
