Answer:
f = 3.97 Hz
Explanation:
Given that,
Centripetal acceleration,
The radius of motion is 0.02 m
The formula for the centripetal acceleration is given by :
The speed of an object in a circular path is given by :
t is time period
Also, f=1/t (f is frequency)
Hence, the frequency of motion s 3.97 Hz.
Answer:
The formula is: weight/mass = gravitational field strength. On Earth the gravitational field strength is 10 N/kg.
Explanation:
Answer:
A voltmeter measures the potential difference (or voltage) across a circuit element.
An ammeter measures the electric current across a circuit element.
Explanation:
This because a voltmeter is an electric device use to measure voltage or potential difference in a circuit. It is connected parallel to a device in the circuit. voltage is measure in volts.
An ammeter is an electric device that is use to measure currents in a circuit even to the smallest part of current. Current is measure in Ampere and ammeter is connected in direct series to a device in a circuit.
Answer:
Force on the singly charged ion will be
Explanation:
We have given electric field E = 8 MN/C
So electric field in N/C will be
It is given that ion so charge on ion will be equal to
We have to find the electric force on the ion
Electric force is equal to , here q is charge and E is electric field
So force on the charge will be equal to
So force on the singly charged ion will be
