Explanation:
To understand why the correct answer is option 'B', let's break down the problem step by step.
The Compass:
A compass is a navigational tool that points towards the Earth's magnetic north pole. It consists of a magnetized needle which aligns itself with the Earth's magnetic field. The needle has two ends - a red portion and a white portion. The red portion of the compass needle always points towards the Earth's magnetic north pole.
The Starting Point:
Arpita is standing in the middle of a crossroad with a compass. Since the red portion of the compass needle is pointing towards her, it means her current direction is towards the north.
The Desired Direction:
Arpita wants to go towards the east. East is located to the right of north when facing the north direction.
The Correct Option:
To go towards the east, Arpita needs to turn left and then go straight. Here's why:
Option A: Right and then go straight
If Arpita turns right, she will be turning towards the west direction. Going straight from there will take her towards the west, which is the opposite direction of east. Hence, option A is incorrect.
Option B: Left and then go straight
If Arpita turns left, she will be turning towards the west direction. Going straight from there will take her towards the east, which is the desired direction. Hence, option B is correct.
Option C: Right and then go left
If Arpita turns right and then goes left, she will be making a U-turn and ending up in the opposite direction. This will take her towards the west, which is the opposite direction of east. Hence, option C is incorrect.
Option D: Left and then go right
If Arpita turns left and then goes right, she will be making a U-turn and ending up in the opposite direction. This will take her towards the west, which is the opposite direction of east. Hence, option D is incorrect.
Conclusion:
Based on the analysis above, the correct answer is option 'B' - Arpita should turn left and then go straight to go towards the east.
