Q: A device that can be used to test whether an object is carrying a charge or not is known as:
  • A. microscope
  • B. gyroscope
  • C. electroscope
  • D. kaleidoscope
Correct Answer: Option C - Instrument Uses Microscope – It is an instrument that is used to magnify small objects. Gyroscope – A gyroscope is a device used for measuring or maintaining orientation and angular velocity. Electroscope – It is an instrument used to detect the presence of electric charge on a body. Kaleidoscope – A kaleidoscope is an optical instrument with two or more reflecting surfaces tilted to each other at an angle, so that one or more objects on one end of the mirrors are seen as a regular symmetrical pattern when viewed from the other end, due to repeated reflection.
