Question

There are two force vectors, one of 5 N and other of 12 N at what angle the two vectors be added to get resultant vector of 17 N, 7 N and 13 N respectively

• A. 0⁰, 180⁰ and 90⁰
• B. 0⁰, 90° and 180⁰
• C. 0⁰, 90⁰ and 90⁰
• D. 180⁰, 0⁰ and 90⁰

Answer 1

Answer: (A)

0⁰, 180⁰ and 90⁰

Answer 2

For 17 N both the vector should be parallel i.e. angle between them should be zero.

For 7 N both the vectors should be antiparallel i.e. angle between them should be 180⁰

For 13 N both the vectors should be perpendicular to each other i.e. angle between them should be 90⁰
