Given vec A+ vec B+ vec + vec D=0, can ...

Given ` vec A+ vec B+ vec + vec D=0`, can the magnitude of ` vec A + vec B + vec C` be equal to the magnitude of vec D` Explain.

Text Solution

Verified by Experts

Yes, Given ` vec A + vec B+ vec C + vec D =vec 0`
or ` vwc A + vec B +vec C+ vec D =- vec D`
Hence magitude of (vec A + vec B= vec C) must be equal to the magnitude of vec D`.
