Question

if a unit vector is represented by 0.5 ICAP + 0.8 J cap + c k cap the value of scenes

Answer 1

â = 0.5î + 0.8j + ck
$a = 1 \\ \sqrt{({0.5}^{2}) + ( {0.8}^{2}) + {c}^{2} } = 1 \\ ({0.5}^{2}) + ( {0.8}^{2}) + {c}^{2} = 1 \\ 0.25 + 0.64 + {c}^{2} = 1 \\ {c}^{2} = 1 - 0.89 = 0.11 \\ c = \sqrt{0.11}$
