Question

A man measures the period of a simple pendulum inside a stationary lift and finds it to be T sec. If the lift accelerates upwards with an acceleration g divided by 4, then the period of the pendulum will be

  1. T    
  2. fraction numerator T over denominator 4 end fraction    
  3. fraction numerator 2 T over denominator square root of 5 end fraction    
  4. 2 T square root of 5    

The correct answer is: fraction numerator 2 T over denominator square root of 5 end fraction


    In stationary lift T equals 2 pi square root of fraction numerator l over denominator g end fraction end root
    In upward moving lift T to the power of ´ end exponent equals 2 pi square root of fraction numerator l over denominator left parenthesis g plus a right parenthesis end fraction end root
    (a equalsAcceleration of lift)
    rightwards double arrow fraction numerator T to the power of ´ end exponent over denominator T end fraction equals square root of fraction numerator g over denominator g plus a end fraction end root equals square root of fraction numerator g over denominator open parentheses g plus fraction numerator g over denominator 4 end fraction close parentheses end fraction end root equals square root of fraction numerator 4 over denominator 5 end fraction end root rightwards double arrow T to the power of ´ end exponent equals fraction numerator 2 T over denominator square root of 5 end fraction
