The acceleration will be positive in ....

The acceleration will be positive in .

A

`(I) and (III)`

B

`(I) and (IV)`

C

` (II) and (IV)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
In I, slope is negative and its magnitude is decreasing with time. It means slope is increasing mumerically, So velocity is inreasing towards right and so acceleration is positve.
In IV slope is positive and its magnitude is increasing with time, So velocity is increasing towards right, and so acceleration is positive.
