In which of the following fields is repulsion NOT experienced?

Analyze the question: We need the field in which repulsion never occurs, meaning the field that only attracts.

Explain the concept:

• Electric field: Like charges repel (+ and +, or − and −). Unlike charges attract. So repulsion is experienced.
• Magnetic field: Like poles repel (N and N, or S and S). Unlike poles attract. So repulsion is experienced.
• Gravitational field: Masses only attract one another. No negative mass has ever been observed, so gravitational repulsion is never experienced.

Solution:

• Electrical: repulsion occurs, so it is not the answer.
• Magnetic: repulsion occurs, so it is not the answer.
• Gravitational: only attraction occurs, so repulsion is NOT experienced here.

The question asks where repulsion is NOT experienced, and the answer is the gravitational field only.

Checking the options:

• A: Electrical does show repulsion, so it is wrong.
• B: Gravitational only is correct.
• C: Magnetic does show repulsion, so it is wrong.
• D: Both show repulsion, so it is wrong.
• E: Includes magnetic, which shows repulsion, so it is wrong.

**Answer: B. Gravitational only.

Tip: Remember "Gravity only pulls, never pushes." Electric charges and magnetic poles both have two types (+/− and N/S), so they can attract or repel. Mass has only one type, so gravity can only attract.
