Question

Figure below shows a body of mass M moving with the uniform speed on a circular path of radius, R. What is the change in acceleration in going from P subscript 1 end subscript to P subscript 2 end subscript

  1. Zero    
  2. v to the power of 2 end exponent divided by 2 R    
  3. 2 v to the power of 2 end exponent divided by R    
  4. fraction numerator v to the power of 2 end exponent over denominator R end fraction cross times square root of 2    

The correct answer is: fraction numerator v to the power of 2 end exponent over denominator R end fraction cross times square root of 2


    capital delta a equals 2 a sin invisible function application open parentheses fraction numerator theta over denominator 2 end fraction close parentheses= 2 a cross times sin invisible function application 4 5 degree equals square root of 2 a equals square root of 2 fraction numerator v to the power of 2 end exponent over denominator R end fraction

    A train has just complicated a U-curve in a track which is a semicircle. The engine is at the forward end of the semi circular part of the track while the last carriage is at the rear end of the semicircular track. The driver blows a whistle of frequency 200 Hz. Velocity of sound is 340 m/sec. Then the apparent frequency as observed by a passenger in the middle of a train when the speed of the train is 30 m/sec is
