Problem

A particle moves in a circle of radius

5\,\text{cm}

with constant speed, starting from the point

(5\,\text{cm},0)

and moving anticlockwise. Its projection on the vertical diameter is noted. When the particle has rotated through an angle of

60^{\circ}

, the displacement of the projection from the centre of the circle is a)

2.5\,\text{cm}

-4.3\,\text{cm}

4.3\,\text{cm}

5.24\,\text{cm}
