The following are four different relations about displacement, velocity, and acceleration for the motion of a particle in general. Choose the incorrect statement(s):
(a) vav = 1/2 [v(t1) + v(t2)]
(b) vav = r(t2)-r(t1)/t2-t1
(c) r = 1/2 [v(t2)-v(t1)](t2-t1)
(d) aav = v(t2)-v(t1)/t2-t1
1. (a), d)
2. (a), c)

NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyAssertion (A): | If two particles move with uniform accelerations in different directions, then their relative velocity changes in direction. |
Reason (R): | Since the acceleration are in different directions, there is a relative acceleration and hence the relative velocity changes. |
1. | (A) is true but (R) is false. |
2. | (A) is false but (R) is true. |
3. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
4. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
