A wheel is rolling on a horizontal plane. At a certain instant it has a velocity `v` and acceleration `a` of `CM` as shown in figure . Acceleration of

Options

A. `A` is vertically upwards
B. `B` may be vertically down-wards
C. `C` cannot be horizontal
D. some point on the rim may he horizontal leftwards

Answer

A, B, C, D

Explanation

At A:

For a rollihng wheel `a=Ralpha`
Therefore option a correct. At `B`:

`If (V^(2))/r=a` then `a_(B)` may be vertically downwards Therefore, option b correct.
At `C`:

Therfore, option c is correct
Consider this correct

Therfore option d correct.
