The angular acceleration of particle moving along a circular path with uniform speed
A uniform but non zero
B zero
C variable
D such as can not be predicted from given information

The correct option is B zero
The velocity of the particle is constant i.e $\mathrm{v}=$ constant
Using $\mathrm{v}=\mathrm{rw} \quad \Longrightarrow \mathrm{w}=$ constant
$\therefore$ Angular acceleration $\quad a=\frac{\mathrm{dw}}{\mathrm{dt}}=0$

At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north. The north tip of the magnetic needle of a dip circle placed in the plane of magnetic meridian points above the horizontal. The horizontal component of the earth’s field is measured to be $0.16 \mathrm{G} .$ Specify the direction and magnitude of the earth’s field at the location.At a certain location in Africa, a compass points $12^{\circ}$ west of the geographic north.
