Answers
Answer:
(3) Answers is right
Step-by-step explanation:
hop it help
If the vectors a=3i+j-2k, b=-i+3j+4k , c=4i-2j-6k form the sides of the triangle the the lenght of the median bisecting the vector c is
√6 units
Therefore, Option (2) is correct
Step-by-step explanation:
The sides of the triangle are given by
Here,
The half of the vector c will be
if the median vector is
Then
Therefore,
Hence, the length of the median bisecting vector c is √6 units
