PQ is a smooth inclined plane whose angle of inclination can be varied in such a way that point Q remains fixed P can move on a vertical line PR A particle slides from rest from point P At different values of 0 time for descent t from P to Q is noted The following statement is true about t A minimum value of t is 2 B t is minimum when 8 approaches 90 C to decreases continuously as 8 is increased D t first increases then decreases as 0 is increased A particle at a height h from the ground is projected with an angle 30 from the borontal ground making angles 45 wil
