Two conducting spheres have identical radii. Initially they have charges of opposite sign and unequal magnitudes...
Two conducting spheres have identical radii. Initially they have charges of opposite sign and unequal magnitudes with the magnitude of the positive charge larger than the magnitude of the negative charge. They attract each other with a force of 0.27 N when separated by 0.4 m. The spheres are suddenly connected by a thin conducting wire, which is then removed. Now the spheres repel each other with a force of 0.045 N. A.) What is the magnitude of the positive...

Two insulating spheres have radii 0.300 cm and 0.500 cm, masses 0.250 kg and 0.700 kg, and uniformly distributed charges of -2.00 µC and 2.50 µC. They are released from rest when their centers are separated by 1.00 m. (a) How fast will each be moving when they collide? (Hint: Consider conservation of energy and of linear momentum.) (b) If the spheres were conductors, would the speeds be greater or less than those calculated in part (a)? (Note: Assume a...

Rolling and Torque Two spheres of the same mass are positioned on a 100 meter ramp with at 20 degree incline. Both spheres have a radius or 5 m and mass of 1000 kg (HUGE SPHERES, think Indiana Jones). The difference is how the mass is distributed. One sphere is completely solid with mass equally distributed throughout it. The second mass has all of its mass distributed at the edge of its radius in a thin shell. So, one...

equal masses as shown in the figure. The length of the strings are
equal and the angle (shown in the figure) with the vertical is
identical. Find the magnitude of the charge on each sphere. The
acceleration of gravity is 9.8 m/s 2 and the value of Coulomb’s
constant is 8.98755 × 109 N · m2 /C 2 . Answer in units of C.
