In lamp and scale arrangement for measures the angle of deflection, the scale is:
Correct answer: A. Translucent
- A. Translucent
- B. Mass scale
- C. Transparent
- D. None of these
Explanation
Translucent materials allow some light to pass through, but they also scatter or diffuse the light, making objects on the other side appear blurry or less distinct. In the context of a lamp and scale arrangement for measuring the angle of deflection in a galvanometer, using a translucent scale could make it difficult to accurately read the deflection angle. The scale markings may not be clearly visible due to the scattering of light, leading to potential errors in measurement.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
