Question

28
If a, b and c be the distances travelled by the body during xth, yth and zth second from start, then which of
the following relations is true?
(1) aly - z) + b(z - x) + c(x - y) = 0
(2) a(z - x) + b(x - y) + c(y - z) = 0
(3) a(x - y) + b(y – z) + c(z - x) = 0
(4) ax + by + cz = 0​

Answer 1

ax+by+cz=0. Because body come to its initial state so displacement of body is zero
