A) \[\sqrt{3\,(P+1)}\]
B) \[\sqrt{2{{P}^{2}}+3}\]
C) zero
D) \[P(\sqrt{2}+1)\]
Correct Answer: D
Solution :
Let the vectors are OA , OB and OC shown below. Given that, OA = OB = OC = P Clearly, the resultant ofOA and OC willbe in the direction of OB. The magnitude of OA + OC \[=2P\cos 45{}^\circ =P\sqrt{2}\] Now, magnitude of resultant vector along OB is \[P+P\sqrt{2}=P(\sqrt{2}+1)\]You need to login to perform this action.
