Question

Choose the correct statements.
a) The product of a scalar and a vector is a vector quantity.
b) Two vectors of different magnitude can be combined to give a zero resultant.
c) Three vectors of different magnitudes may be combined to give a zero resultant.
d) All the above are wrong statements.

• A. a & b are correct
• B. a & c are correct
• C. a & d are correct
• D. b & c are correct

Answer 1

The correct option is B a & c are correct

The product of a scalar and a vector is always a vector quantity. Here the scalar will change the magnitude of the vector. So point $a$ is correct. Due to triangle rule of vector addition the point $c$ is correct.
