To solve this problem we will apply the concept of balance of Forces in the body. For such an effect the centripetal force must be equivalent to the electrostatic force of the body, therefore
Here
m = Mass of electron
r = Distance between them
k = Coulomb's constant
= Charge of proton
= Charge of electron
v = Velocity
Rearranging to find the velocity we have that,
Replacing,
Therefore the speed of the electron is
Answer:
I don't exactly understand this but the child should hear a beep lower than 500 hz when he/she moves the car further away. If you don't find my answer appealing sorry but I don't do physics.
Explanation:
Answer:
Push and pull both are forces , but the difference is in their direction at which it is applied . If the force applied in the direction of motion of the particle then we call it as push . If that force applied in the direction OPPOSITE to the motion of particle then it is termed as pull
Answer:
The potential at a distance of 0.9 m is 266.67 V.
Explanation:
Charge = Q
Potential is 400 V at a distance 0.6 m .
Let the potential is V at a distance 0.9 m.
Use the formula of potential.
