What is the equivalent resistance between the points A and B of the network?

To solve for the equivalent resistance between points A and B, we first simplify the given resistances using series and parallel combinations.
Start by analyzing the network step by step: 1. Combine the resistances that are in series. 2. Combine the resistances that are in parallel. Once simplified, the equivalent resistance turns out to be 8 \( \Omega \).
Final Answer: 8 \( \Omega \).
Given below are two statements: one is labelled as Assertion (A) and the other one is labelled as Reason (R).
Assertion (A): Emission of electrons in the photoelectric effect can be suppressed by applying a sufficiently negative electron potential to the photoemissive substance.
Reason (R): A negative electric potential, which stops the emission of electrons from the surface of a photoemissive substance, varies linearly with the frequency of incident radiation.
In light of the above statements, choose the most appropriate answer from the options given below:
