From definition of centre of mass, calculate the distance d for the given system.

1. 16 × 1.12 × 10^-10 + 12 × 0
2. 16 × 1.12 × 10^-10
3. 28
4. 0.64 × 10^-10 m

Correct answer: 16 × 1.12 × 10^-10

Solution

The center of mass is calculated using the weighted average of distances based on masses. Here, the correct formula simplifies to option B.
