Stanley and Dexter each have a balloon. Stanley rubs his balloon with a wool cloth, giving it a negative charge, while Dexter does not rub his balloon, keeping its charge neutral. According to the law of electric charges, what will happen when they bring their balloons close to each other?
The balloons attract each other because a charged object will attract a neutral object.
The balloons repel each other because a charged object pushes away neutral objects.
The balloons will have no reaction because an object must be charged to experience an electric force.
The balloons attract each other because neutral objects always carry a hidden opposite charge.
The balloons repel each other since Stanley's balloon is negatively charged.
The electrostatic force between the two balls is 3.4 × 10–7 N. If the distance between the charges
is tripled but the size of the charges remains the same, the force between them will be:
3.1 × 10–6 N
3.8 × 108 N
2.6 × 107 N
3.8 × 10–8 N
1.1 × 10–7 N
Which of the following is NOT a similarity or difference between Coulomb's law and Newton's law of universal gravitation?
The forces act along the line joining the centers of the masses or charges.
The electric force can attract or repel, depending on the charges involved, whereas the gravitational force can only attract.
The universal constant G is very small, and in many cases, the gravitational force can be ignored. Coulomb's constant k is very large, so even small charges can result in noticeable forces.
Coulomb's law is the product of two masses, whereas Newton's law of universal gravitation is the product of two charges.
The size of the force is the same as the force that would be measured if all the mass or charge is concentrated at a point at the center of the sphere.
