Statement-1: If \[|{{z}_{1}}|=30,|{{z}_{2}}-(12+5i)|=6,\] value of \[|{{z}_{1}}-{{z}_{2}}|\]is 49. |
Statement-2: If\[{{z}_{1}}-{{z}_{2}}\]are two complex numbers, then \[|{{z}_{1}}-{{z}_{2}}|\,\le \,|{{z}_{1}}|+|{{z}_{2}}|\] and equality holds when origin, \[{{z}_{1}}\]are \[{{z}_{2}}\]collinear and \[{{z}_{1}},{{z}_{2}}\]are on the opposite side of the origin |
A) Statement-1 is false, Statement-2 is true
B) Statement-1 is true, Statement-2 is true, and Statement-2 is a correct explanation for Statement-1
C) Statement-1 is true, Statement-2 is true; Statement-2 is not a correct explanation for Statement-1.
D) Statement-1 is true, Statement-2 is false.
Correct Answer: C
Solution :
\[{{C}_{1}}{{C}_{2}}=13\] \[{{r}_{1}}=30,{{r}_{2}}=6\]\[{{C}_{1}}{{C}_{2}}<{{r}_{1}}-{{r}_{2}}\]You need to login to perform this action.
