Study Notes
Physics Fundamentals
- The fundamental units considered in the given question are force (F), length (L), and time (T).
Friction and Normal Force
- The minimum value of the coefficient of friction (μ) required for the cube to not slip is not specified, but it depends on the angle between the cube and the floor.
- The angle between one side of the cube and the floor is 45°.
- The normal force (N) and the gravitational force (Mg) on the cube at a 45° angle are related by the equation N = Mg cos(45°).
Dimensions of Mass
- The dimension of mass (M) in terms of fundamental units is [M] = [F L T^-2].
Coefficient of Friction
- The value of coefficient of friction (μ) is impossible to balance the cube for any value of μ if it is infinite.
Instrument Errors
- The zero error of the instrument described in the text is not specified.
Projectile Motion
- A body projected up with a velocity equal to 3/4 of the escape velocity from the surface of the earth reaches a height of 1.125 times the earth's radius from the center of the earth.
Prism and Refraction
- The angle of deviation for a light ray incident almost normally on the first face of a thin prism with different medium on its either side is not specified, but it depends on the angles of incidence and refraction.
- The overall deviation, δ, for a thin prism with different medium on its either side is given by the equation δ = (μ - 1)A, where μ is the refractive index and A is the angle of incidence.
Transformers
- The current in the primary coil of a 100% efficient transformer is given by the equation I1 = I2 * (N2 / N1), where I1 is the current in the primary coil, I2 is the current in the secondary coil, N1 is the number of turns in the primary coil, and N2 is the number of turns in the secondary coil.
Instrument Diagrams
- R1 represents a resistance in the instrument described in the text.
- v represents the velocity of the body projected up with a velocity equal to 3/4 of the escape velocity from the surface of the earth.
- The instrument shown by diagram (II) is in series when both rods are together.
