You pull your t-shirt out of the clothes dryer and note that 1502 particles have become attached, each of which could be either an electron or a proton. Your t-shirt has a net charge of −4.71 ✕ 10−17 C. (a) How many electrons are attached to your t-shirt?_______ electrons(b) What is the total mass of all the protons attached to your shirt?_______ kg

Two small, positively charged spheres have a combined charge of 33.0 × 10-5 C. If each sphere is repelled from the other by an electrostatic force of 1.00 N when the spheres are 1.80 m apart, what is the charge on the sphere with the smaller charge? Number Units

A platypus foraging for prey can detect an electric field as small as 0.002 N/C. To give an idea of the sensitivity of the platypus’s electric sense, how far from a +10 nC point charge does the field have this magnitude?

Two identical balloons are inflated and charged in the same manner. They are tied by threads and hung from the same pivot point on the ceiling. The balloons hang down, with the threads making an angle of 14° with each other and the balloons being separated by a distance of 58 cm (center-to-center). Each balloon has a charge of - 3.5x10-7 C. Draw a free-body diagram for the balloons and consider them to act as point objects.

What is the net charge on a sphere that has the following? (a)    6.33  106 electrons and 7.71  106 protons(b)    215 electrons and 111 protons

Two identical balloons are inflated and charged in the same manner. They are tied by threads and hung from the same pivot point on the ceiling. The balloons hang down, with the threads making an angle of 13.9° with each other and the balloons being separated by a distance of 71.9 cm (center-to-center). Each balloon has a charge of -3.59x10-7 C. Draw a free-body diagram for the balloons and consider them to act as point objects. a. Calculate the force of electrical repulsion between the balloons. Force of Repulsion x-Component of Tension b. What is the horizontal component of force in the thread that supports either one of the balloons? y-Component of Tension d. What is the mass of either one of the balloons? x10^ Balloon Mass c. What is the vertical component of force in the thread that supports either one of the balloons? x10^ x10^ N x10^ kg N N I I

Two objects charged with an equal amount of charge interact with each other with a force of 3.68 Newton when separated by a distance of 13.3 cm. Determine the magnitude of the charge on each object. Answer: x10-6 C Enter only the coefficient of the scientific notation. For example, you'd enter just just 1.27 if you get 1.27x10-⁹.

Two small pith balls, each with a charge of + 4.89  µC and + 4.17  µC, repel each other with a force of 3.12 N. Determine the distance separating the two pith balls. Give your answer in meters.
