The time of flight of a body becomes `n` times the original value if its speed is made `n` times.
This due to the range of the projectile which becomes `n` times.

In the following questions, a statement of assertion is followed by a statement of reason (R). Mark the correct choice as : Assertion. For a projectile the time of flight of a body becomes n times the original value if its speed is made n times. Reason. For a projectile, this is due to the range of the projectile which becomes n times.

Relate range of the projectile in terms of time of flight.

What is time of flight and range of a projectile?

STATEMENT-1: When speed of projection of a body is made n-times, its time of flight becomes n times. STATEMENT-2: This is because range of projectile become n times.

If the accelaration due to gravity becomes 4 times its original value, then escape speed

The amplitude of damped oscillator becomes 1/3 of original value in 2s . Its amplitude after 6s is 1//n times the original. The value of n is
