Illustrate at what angle should a curve of radius 140 m be banked, so cars can travel safely at 33 m/s without relying on friction?
A 2.75-gram air inflated balloon is given an excess negative charge, q1 = -3.00 × 10-8 C, by rubbing it with a blanket. It is found that a charged rod can be held above the balloon at a distance of d = 5.20 cm to make the balloon float. In order f..
