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 |

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!

0.25+.64+c^2=1
then c=(11)^1\2

The formula is _/a^2+b^2+c^2 = Magnitude Put value in the above formula _/(0.5)^2+(0.8)^2+c^2=1By calculating we get -/0.11

|a+b+c|=1
√0.5²+0.8²+c²=1
squaring both sides
0.5²+0.8²+c²=1
0.25+0.64+c²=1
c²+0.89=1.00
c²=0.11
c=√0.11
√0.5²+0.8²+c²=1
squaring both sides
0.5²+0.8²+c²=1
0.25+0.64+c²=1
c²+0.89=1.00
c²=0.11
c=√0.11
