Question

.
#v) If the line r = (i - 2 j + 3k) + (2 î + j + 2k) is parallel to
the plane r.(3i
-2j + mk)=10, then value of m is
sa - 2
(b) 2
(c) + 2
(d) 0​

Answer 1

Answer:

m=0

Step-by-step explanation:

a=i-2j+3k

b=2i+j+2k

c=3i-2j+mk

a*b*c= 1(2)(3)+(-2)(1)(-2)+(3)(2)(m)=10

=6+4+6m=10

=10+6m=10

=6m=10-10

=6m=0

=m=0/6

=m=0
