Per NCERT §3.4 eqn 3.1, vector addition obeys which property by symmetry?
ANo symmetry
BAnticommutative (A+B = -(B+A))
CCommutative (A+B = B+A)
DDistributive only
Answer & Solution
Correct answer: C. Commutative (A+B = B+A)
NCERT eqn 3.1 + Fig 3.4: triangle method gives same R whether we add A first or B first. Vector addition is commutative.
