In summary, the speed of the bead at plate Y is 2.24x10^4 m/s, calculated using the equation v=sqrt(2*E/m) where E is the electric potential difference and m is the mass of the bead.

Hello,
I am wondering if you could help me overcome this problem
in this case we are referring to types of weavers,
Another design of machine uses beads of oils and two metal plates X and Y.
The potential difference between these plates is 5.0x10^3V
Each bead of oil has a mass of 4.0x10^-5 Kg and is given a negative charge of 6.5x10^-6 C.
The bead accelerates from reat at plate X and passes through a hole in plate Y.

Neglecting effects of air friction, calculate the speed of the bead at plate Y.
Any help would be appreciated.

The speed of the bead at plate Y can be calculated using the equation v=sqrt(2*E/m), where E is the electric potential difference and m is the mass of the bead. Plugging in the given values, we get: v=sqrt(2*(5.0x10^3V)/(4.0x10^-5Kg)) = 2.24x10^4 m/s
 

FAQ: What is the Speed of a Charged Bead Passing Through Two Metal Plates?

What is potential difference?

Potential difference, also known as voltage, is the difference in electric potential between two points in an electrical circuit. It is measured in volts (V) and represents the amount of energy required to move a unit of electric charge from one point to another.

How is potential difference related to electric current?

Potential difference is directly related to electric current. In fact, potential difference is what causes electric current to flow through a circuit. The higher the potential difference, the greater the flow of electric current.

What factors affect potential difference?

The main factors that affect potential difference are the voltage of the power source and the resistance of the circuit. The higher the voltage, the greater the potential difference, and the lower the resistance, the greater the potential difference.

How is potential difference measured?

Potential difference is measured using a voltmeter, which is a device that measures the voltage between two points in an electrical circuit. The voltmeter is connected in parallel to the component or circuit being measured.

What is the relationship between potential difference and speed?

Potential difference does not directly affect speed. However, it does impact the flow of electric current, which in turn can affect the speed of an electrical device or component. Higher potential difference can result in a higher flow of electric current, which can increase the speed of an electrical device.
