(a) What will an object weigh on the Earth's surface if it weighs 160 N on the Moon's surface? (b) How many Earth radii must this same object be from the center of Earth if it is to weigh the same as it does on the Moon?

Explanation

To solve the problem step by step, let's break it down into two parts as given in the question.

### Part (a): Weight on Earth's Surface

1. **Given Information**:
- Weight of the object on the Moon (W_moon) = 160 N

2. **Understanding the relationship between weights on the Moon and Earth**:
