Match the description on the right with the force on the left.
Marat540 [252]

Magnetic force - B.

Electrical force - A.

Gravitational force - D.

Contact force - C.

<h3><u>Explanation:</u></h3>

When a charge moves about its path, it produces a magnetic force around it. This magnetic field is perpendicular to the axis of movement of the charge and is directly proportional to the amount of charge, speed of the charge, and inversely proportional to distance between the charge and the point of measurement. Michael Faraday discovered this phenomenon.

Electrical force of attraction or repulsion is seen between the two charged bodies, or one charged body and one uncharged body which can induce charge to the uncharged body. The attraction or repulsion between the charged bodies are seen if the bodies are close enough, and this is called electrical force.

The gravitational force is also a non contact force that is seen between two bodies which is always attractive in nature and is seen between any two bodies.

A contact force like friction is a type of force that takes place only when two bodies are in contact with each other.

  • Compound light microscopes have higher magnification.

Thus, the correct option for this question is C.

<h3>What is a Microscope?</h3>

A microscope may be defined as a type of laboratory instrument that is significantly utilized to examine or observe objects that are too small to be visualized by the unaided eye.

Dissecting microscopes possess a lower magnification power as compared to compound light microscopes. Due to this, dissecting microscopes are used to visualize larger objects like tissues. Compound light microscopes use more than one glass lens. These types of microscopes are used to examine living cells.

Therefore, a compound light microscope has higher magnification is a statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope. Thus, the correct option for this question is C.
