The instrument which is used to detect a charged body is known as an eletroscope. Now you can visit Google images or any other site and find out the diagram... :)
An electroscope is an instrument used to detect static electricity.
Sensitivity describes the smallest change an instrument can detect. Range describes the largest change an instrument can detect.
A magnetometer
hmmm
It is Thermoscope
detect charged particles
An electroscope is an instrument used to detect static electricity.
a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge.
One instrument that used to detect Tsunami is a deep ocean tsunami detection buoys.
Sensitivity describes the smallest change an instrument can detect. Range describes the largest change an instrument can detect.
A magnetometer
The word that means hard to detect or describe is elusive.
The explorer is used by the dentist to detect decay.
hmmm
Sonar
a wee gee board
It is Thermoscope
