A rod of length units slides with its ends on the coordinate axes. The locus of the midpoint of the rod is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Let Aa,0 & B0,b are the end points of the rod and Ph,k be the mid-point. So, a2=h & b2=k ⇒a=2h & b=2k Length of the rod is given 6 units ⇒0-a2+b-02=6 ⇒a2+b2=62 ⇒2h2+2k2=62 ⇒4h2+4k2=36 So, locus of P is…
