Question
A vector which makes equal angles with the vectors 
is -
is -Options
A. 
B. -
C.
D.
Solution
Let 
it makes equal angle with
then
= y
4x + 5y + 3z = 0 ... (i)
x - 5y + 2z = 0 ... (ii)
from (i) & (ii)
x = - z & x = -5y
.
it makes equal angle with
then = y4x + 5y + 3z = 0 ... (i)
x - 5y + 2z = 0 ... (ii)
from (i) & (ii)
x = - z & x = -5y
