Consider the following vectors. Choose the correct statement.
Options
- AE=A-B and A=D+C
- B-E=-A+B and A=-D+C
- CE=-A-B and E=-B+D+C
- DE=-A-B and E=-B+C-D
Correct answer
B. -E=-A+B and A=-D+C
Step-by-step solution
The given situation for connection of vectors is given as According to rule of vector addition, In P Q R , A = B + E E = A - B - E =- A + B (i) Again, according to rule of vector addition, In P S R , C = A + D A = C - D A =- D + C (ii) From Eqs. (i) and (ii), we see that option (b) is correct.
