The value of

k

so that

x^2+y^2+k x+4 y+2=0

and

2\left(x^2+y^2\right)-4 x-3 y+k=0

cut orthogonally, is

View answer and explanation

Correct option: C

\frac{-10}{3}

Option C (

\frac{-10}{3}

) is correct because the condition for orthogonal intersection of two circles (

) is applied to find the value of

k
