Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Correct answer: Voltmeter
Explanation:
A voltmeter is an electrical measuring instrument used to measure the potential difference (voltage) or electromotive force (emf) between two points in an electric circuit.
Other options:
- Ammeter: measures electric current.
- Calorimeter: measures heat.
- Barometer: measures atmospheric pressure.
Hence, the correct answer is: Voltmeter.

- A particle of charge \( q \) is moving with a velocity \( \vec{v} \) at a distance \( d \) from a long straight wire carrying a current \( I \) as shown in the figure. At this instant, it is subjected to a uniform electric field \( \vec{E} \) such that the particle keeps moving undeviated. In terms of unit vectors \( \hat{i}, \hat{j}, \) and \( \hat{k} \), find:
the magnetic field \( \vec{B} \),
the magnetic force \( \vec{F}_m \), and
