13. Two vectors having magnitude 12 and 13 are inclined at an angle 45 to each other. Find theiresultant vector. |

Answer» approximately 23 a = 12 ; b = 13 ; R = ? ; Q = 45° => R = √ ( a^2 + b^2 + 2 a . b . cos Q ) => R = √ ( 12^2 + 13^2 + 2 . 12 . 13. cos 45 ° ) => R = = √[144 + 169 + 312 (1/√2)] => R = √(313 + 220.65) => R = √(533.65) => R = 23.10 |
