Assertion (A): IF the angle of elevation of an aeroplane from a point on the ground is 60∘. After 15 s, the angle of elevation changes to 30∘. If the aeroplane is flying at a constant height of 1500√3m, then speed of aeroplane is 200 m/s Reason: (R): Speed=DistanceTime Which of the following is true?

Assertion (A): IF the angle of elevation of an aeroplane from a point

1.	Assertion (A): IF the angle of elevation of an aeroplane from a point on the ground is 60∘. After 15 s, the angle of elevation changes to 30∘. If the aeroplane is flying at a constant height of 1500√3m, then speed of aeroplane is 200 m/s Reason: (R): Speed=DistanceTime Which of the following is true?
Answer» Assertion (A): IF the angle of elevation of an aeroplane from a point on the ground is $60^{\circ}$ . After 15 s, the angle of elevation changes to $30^{\circ}$ . If the aeroplane is flying at a constant height of $1500 \sqrt{3}$ m, then speed of aeroplane is 200 m/s Reason: (R): $S p e e d = \frac{D i s t a n c e}{T i m e}$ Which of the following is true?
