Question

Assertion (A): When we travel to a time zone west of us, we set our watches one hour behind us.

Reason (R): The Earth rotates from west to east.

विकल्प

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true and R is the correct reason for A.

Explanation:

When we travel westward, we set our watch one hour behind because Earth rotates from west to east. The Earth’s rotation causes time zones and time differences based on longitude. Moving west means the local time is earlier, so clocks are set back by one hour accordingly.
