The moment of inertia of the plate about the x-axis is

  1. fraction numerator M L to the power of 2 end exponent over denominator 8 end fraction    
  2. fraction numerator M L to the power of 2 end exponent over denominator 32 end fraction    
  3. fraction numerator M L to the power of 2 end exponent over denominator 24 end fraction    
  4. fraction numerator M L to the power of 2 end exponent over denominator 6 end fraction    

The correct answer is: fraction numerator M L to the power of 2 end exponent over denominator 8 end fraction
