Question

The scaler product of two vectors is maximum when they are: a) Parallel b) Anti-parallel c) Perpendicular

Answer 1

Answer:

when they are perpendicular.

pls mark me brainliest

Answer 2

Answer:

a) parallel

Explanation:

a & b two vectors then scalar product

a • b = |a| |b| cos @

a) parallel ; @ = 0°

a • b = |a| |b| cos 0° = |a| |b

b) Anti-parallel ; @ = 180°

a • b = |a| |b| cos 180° = (-1) |a| |b

c) Perpendicular ; @ = 90°

a • b = |a| |b| cos 90° = 0

hence product is maximum when they are parallel
