اگر ہم پرکشیپک تحریک میں پرواز کے وقت کو دوگنا کرتے ہیں تو ، جس فاصلے پر اس کا احاطہ ہوتا ہے وہ _____ بن جاتا ہے؟
-
A. Quadrupled
-
B. None of these
-
C. Tripled
-
D. Doubled
Explanation
Horizontal range in projectile motion is directly proportional to time of flight when speed is constant.
So, doubling the time results in double the distance covered.
-
A. Remains the same
-
B. Halved
-
C. Doubled
-
D. Becomes four times
Explanation
The horizontal distance or range is given by:
R=ucos(θ)⋅T
where = initial velocity, = angle of projection, and = time of flight.
-
If the range is doubled but the initial velocity and angle remain the same, it implies horizontal velocity is increased, not the time.
-
However, if the range is doubled due to an angle change (e.g., using complementary angles), the time of flight may remain unchanged.
