B. चार गुना / Four times

Step 1

Concept

Force is inversely proportional to square of distance.

Step 2

Why this answer is correct

When distance is halved, the square of distance becomes one fourth.

Step 3

Exam Tip

Therefore force becomes four times. चरण 1: बल दूरी के वर्ग के व्युत्क्रम अनुपात में होता है। चरण 2: दूरी आधी होने पर दूरी का वर्ग एक चौथाई होता है। चरण 3: इसलिए बल चार गुना हो जाता है।
