Summary of Main Ideas and Concepts

The video features a physics faculty member, Shubham Swamy, providing solutions to a medical physics test. The content is focused on solving various physics problems, demonstrating concepts through examples and calculations. The key topics covered include:

• Velocity and Dimensional Analysis:
  • A particle's velocity is expressed in terms of constants and time.
  • The Dimensional Analysis is used to determine if certain quantities are dimensionless.
  • The conclusion is that the correct option regarding the dimensionless quantity is option number two.
• Vernier Caliper and Least Count Calculation:
  • The relationship between the main scale division (MSD) and the vernier scale division (VSD) is discussed.
  • The least count of the Vernier Caliper is derived using the formula: Least Count = 1 MSD - 1 VSD.
  • The calculated least count is 0.25 am, confirming option two as the correct answer.
• Projectile Motion:
  • A particle projected upwards covers a specific distance in a given time.
  • The initial velocity is calculated using the distance formula for Projectile Motion.
  • The maximum height is determined to be 80 meters, with option three being correct.
• Acceleration-Time Graph:
  • The area under the Acceleration-Time Graph represents the change in velocity.
  • The area of a trapezium is used to calculate this change, leading to a final velocity of 12 m/s.
  • This result aligns with option one.
• Vector Analysis:
  • The problem involves two vectors of equal magnitude and their angular bisector.
  • The relationship between the vectors and the resultant is explored, leading to the conclusion that the angle between the two vectors is 120°.
  • Option two is confirmed as the correct answer.

Methodology and Instructions

• Dimensional Analysis:
  • Identify the dimensions of each term in the equation.
  • Use dimensional consistency to determine if a quantity is dimensionless.
• Vernier Caliper Calculation:
  • Use the formula: Least Count = 1 MSD - 1 VSD.
  • Calculate the least count based on the given divisions.
• Projectile Motion:
  • Use the formula for maximum height: \( h = \frac{u^2}{2g} \).
  • Calculate initial velocity using distance covered in a specific time.
• Acceleration-Time Graph:
  • Calculate the area under the graph to find the change in velocity.
  • Use the trapezium area formula to derive the final velocity.
• Vector Analysis:
  • Understand the relationship between vectors and their resultant.
  • Apply trigonometric identities to find the angle between vectors.
