DEAR NIMISH
If
0.5icap+o.8jcap+ckcap is a unit vector then its magnitude should be 1. So the value of C is 0.33
111/2
check it it is 100% correct.
Hello Nimish
modulus of 0.5i+0.8j+C k= √(0.5)2 + (0.8)2 + C2
= √0.25+0.64+C2
= √0.89 + C2
But its a unit vector. therefore it''s magnitude should be equal to 1.
√0.89+C2 = 1
squaring both sides,
0.89+C2= 1
C2= 1-0.89 = 0.11
C = 0.33
All the best!
Hey the answer was right but tell the way to solve it.
0.25+.64+c^2=1
then c=(11)^1\2
