Assertion (A): As the length of the resonant antenna is increased, the number of lobes increases and the direction of the major lobes is closer and closer to the direction of the diode.

Reason (R): As the length increases, the current distribution along the wire becomes more and more uniform.

1. An array of integers
2. An array of string objects
3. An array of arrays
4. An array on integer and strings

1. PCM is not noise resistant
2. PCM requires complex encoding and quantizing circuitry
3. PCM requires large bandwidth

Assertion (A): Feedback control systems offer more accurate control than open loop systems.

Reason (R): The feedback path establishes a link for comparison of input and output and subsequent error correction.

Assertion (A): When an electron is revolving in its orbit and magnetic field is also present, the angular frequency of electron will be affected by the magnetic field.

Reason (R): In the case of electron revolving in its orbit in the presence of magnetic field, the orbital magnetic dipole moment is not affected by the presence of magnetic field.
