A) \[PA+PB+PC=0\]
B) \[PA+PB+2PC=0\]
C) \[PA+PB=PC\]
D) PA + PB = 2PC
Correct Answer: D
Solution :
If C is mid-point of AB and P is the origin, then \[PC=\frac{PA+PB}{2}\] Let P be the origin outside of AB and C be mid - point of AB, then \[PC=\frac{PA+PB}{2}\Rightarrow 2PC=PA+PB\]You need to login to perform this action.
