The mass and diameter of a planet are twice those of earth. The period of oscillation of pendulum planet will be (if it is a second's pendulum on earth)?
کسی سیارے کے بڑے پیمانے پر اور قطر زمین سے دوگنا ہوتا ہے۔ پینڈولم سیارے کے دوچار ہونے کی مدت ہوگی (اگر یہ زمین پر دوسرا لاکٹ ہے)؟
Answer: 2√2 seconds
Explanation
- The formula for the period of a pendulum is T = 2π√(l/g), where l is the length of the pendulum and g is the acceleration due to gravity.
- Since the mass and diameter are doubled, the acceleration due to gravity (g) on the planet will be half that of Earth.
- Therefore, the new period of oscillation will be √2 times the period on Earth, meaning if it was a second's pendulum on Earth, it will be 2√2 seconds on the planet.
