Given three coplanar vectors ` vec A = 2 hat I - hat j , magnitude of the sum of three vectors.

Text Solution

Verified by Experts

Sum of vectrs, ` vec R= vec A+ vec B+ vec C` ltbRgt ` = ( 2 hat i-hat j) + (-3hat i-+2 hat j) + 3 hat j =- hat I + 4 hat j` ltbRgt ` | vec R| = sqrt ((-!)^2 + (4)^2) = sqrt 17` .
