How two metal spheres can be charged by induction?
To charge two metal spheres by induction, bring a charged object near the first sphere, inducing opposite charges in the spheres by polarization. Ground one of the spheres momentarily to allow excess charges to flow and redistribute between the spheres, resulting in both spheres being charged.
What is the distance between two spheres each with a charge?
The distance between two charged spheres affects the strength of the electrostatic force between them, given by Coulomb's law. The force decreases as the distance between the spheres increases. The distance influences the magnitude of the force between the spheres.
How does the electric potential energy between two positively charged particles change if the distance between them is reduced by a factor of 3?
The electric potential energy between two positively charged particles increases by a factor of 9 if the distance between them is reduced by a factor of 3. This relationship is based on the inverse square law, where potential energy is inversely proportional to the square of the distance between charged particles.
How does the electric potential energy between two positive charged particles change if the distance between them is reduced by a factor of 3?
The electric potential energy between two positive charged particles will increase by a factor of 9 (3 squared) if the distance between them is reduced by a factor of 3. This is because the potential energy is inversely proportional to the distance between the charges squared.
What can you tell about the charge signs on spheres?
Spheres can carry positive, negative, or neutral charges. Like charges repel each other (e.g., two positively charged spheres), while opposite charges attract (e.g., a positively charged sphere to a negatively charged sphere). Inducing a charge on a neutral sphere can polarize it temporarily.

How charging by induction can make two metallic spheres oppositely charged?
Charging by induction involves bringing a charged object near a neutral object, inducing a separation of charges in the neutral object. When a negatively charged object is brought near the metallic spheres, electrons in the spheres are repelled to opposite sides, creating a positively charged side facing the negatively charged object and a negatively charged side facing away, resulting in opposite charges on the spheres.

How does the electric potential energy between two charged particles change if one particle's charge is increased by a factor of 2?
The electric potential energy between two charged particles is directly proportional to the product of their charges. If one particle's charge is increased by a factor of 2, the potential energy between the two particles will increase by a factor of 2 as well.
How would you change the distance between two positively charged particles to increase the electric potential energy by a factor of 4?
To increase the electric potential energy of two positively charged particles by a factor of 4, you would need to decrease the distance between the particles by a factor of 2 (since potential energy is inversely proportional to distance). This is because potential energy between charged particles is given by the equation PE = k(q1*q2)/r, where r is the distance between the particles.
Is there any current between two fully charged capacitors?
as far i think,there is no current flowing between two fully charged capacitor.current flow in a capacitor happens until it gets fully charged.if it is fully charged then there is no lack of potential,so no current flow.
There are two 5.0 g spheres each suspended from 1.0 m long threads The spheres repel each other after being charged to 91nC What is the angle theta?
The electrostatic force between the spheres causes them to repel each other. This force creates a tension in the threads, which can be broken down into vertical and horizontal components. By setting the vertical component equal to the gravitational force, you can solve for the angle theta.
What do you use to measure electrical force?
Electric force is the attractive or repulsive force between two charged particles. The potential difference between two points can be measured with a Voltmeter.
What makes the rapid flow of charge through the air between the two oppositely charged clouds?
The rapid flow of charge through the air between two oppositely charged clouds is due to the build-up of electrical potential difference between them. When the potential difference becomes strong enough, it overcomes the resistance of the air and creates a conductive path for the charge to flow as lightning.
