In an equilateral triangle ABC, AL, BM, ...

In an equilateral triangle ABC, AL, BM, and `CN` are medians. Forces along BC and BA represented by them will have a resultant represented by

A

2AL

B

2BM

C

2CN

D

AC

Text Solution

Verified by Experts

The correct Answer is:
B
`vec(B)A+vec(B)C=vec(B)D`
`vec(B)A+vec(B) C=2vec(B)M`.
Hence, the answer is `2BM`.
