QAIPMT-2009-Ph-2182: NEET 2009 Physics - Class 12 AIPMT-2009-Ph-2182 Solution: An explosion blows a rock into three parts. Two parts go off at …

An explosion blows a rock into three parts. Two parts go off at right angles to each other. These two are 1 kg first part moving with a velocity of 12 m s−112\ \text{m s}^{-1} and 2 kg second part moving with a velocity 8 m s−18\ \text{m s}^{-1}. If the third part flies off with a velocity of 4 m s−14\ \text{m s}^{-1} its mass would be: 7 kg 17 kg 3 kg 5 kg

Multiple Choice Options

  • A threshold frequency (υ0)\left( {{\upsilon _0}} \right) ( _ 0 _ )
  • B intensity of light
  • C frequency of light (υ0)\left( {{\upsilon _0}} \right) ( _ 0 _ )
  • D υ−υ0\upsilon - {\upsilon _0} _ _ _ 0 _

Step-by-Step Verified Solution

The number of photoelectrons emitted is proportional to the intensity of incident light. Saturation current _ intensity.
