Question

Assertion (A): All places on a particular meridian will have noon at the same time.

Reason (R): The sun crosses a meridian at noon.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true and R is the correct explanation of A.

Explanation:

• Assertion (A) is true: All places on a particular meridian (a line of longitude) experience noon at the same time, as they are aligned with the same longitudinal position relative to the Sun.
• Reason (R) is also true: The Sun crosses a meridian (the local meridian) at noon, meaning it reaches its highest point in the sky for a given location along that meridian at noon.
