Acceleration Due to Gravity

Time period of a simple pendulum on earth's surface is ' T '. It time period becomes ' xT ' when taken to a height ' 2R2R ' above earth's surface. The value of xx will be (R=(R = radius of earth)

Show answer and solution

Answer: (d)

  1. At h=2Rh = 2R: gh=g(1+2)2=g9g_h = \frac{g}{(1+2)^2} = \frac{g}{9}.
  2. T∝1g⇒T′=T9=3TT \propto \frac{1}{\sqrt{g}} \Rightarrow T' = T\sqrt{9} = 3T
  3. So the answer is (d) x=3x = 3.
