Per NCERT §3.4 (graphical), the parallelogram law of vector addition is best described as which procedure?
AHead of A at tail of B; resultant tail-to-head
BBoth vectors collinear; resultant in same direction
CTails at common origin; resultant along diagonal
DHead of A at head of B; resultant tail-to-tail
Answer & Solution
Correct answer: C. Tails at common origin; resultant along diagonal
NCERT §3.4 Fig 3.6: parallelogram method places tails together; diagonal from origin gives resultant. Equivalent to triangle method.
