Study Notes
JEE Advanced 2024 Part Test II Physics
Induced Current in a Coil
- Magnetic flux linked with a coil is zero during the motion of a ball, resulting in no induced current in the ring.
Capacitor with a Dielectric
- Potential difference between the inner and outer surfaces of a capacitor is the same everywhere.
- Net charge density at each point of the inner surface is the same.
- Induced charge on the inner surface, near the medium, is of opposite nature to the free charge.
- Free charge density at point X (σf) is greater than free charge density at point Y (σ'f).
- σf = kσ'f, where k is a constant.
- σi (induced charge density) = σf / (1 - k), derived from equation (i).
Electric Field in a Capacitor
- Electric field in a capacitor with a dielectric is given by: (σf + σi) / (4πε0r^2).
- In the air gap, the electric field is given by: σ'f / (4πε0r^2).
Note: ε0 is the permittivity of free space, and r is the radial distance from the center of the capacitor.
