Question
Two vectors having equal magnitudes of x units acting at an angle of 45o have resultant 
units. The value of x is
units. The value of x is Options
A.0
B.1
C.√2
D.2√2
Solution
Here, P = x units, Q = xunits, θ = 45o
R = units
We have, R =
or, R =
or,
= 
or,
= 
or, = x ⇒ x = 1
R =
unitsWe have, R =
or, R =
or,
= or,
= or,
= x ⇒ x = 1Create a free account to view solution
