1. In 1990, a French team flew a kit that was 1034m long. Imagine two charges, +2.0 nC and -2.8 nC, at the opposite end of the kite. Calculate the magnitude of the electronic force between them.
2. By 2005 the worlds tallest buildig will be the International Finance Center in Taipei, Republice of China. Suppose a 1.00 charge is placed at both the base and the top of the International Finance Center. If the magnitude of the electronic force streching the building is 4.48*10 -4 N, how tall is the International Finance Center?
3.What is the potential difference between a point 0.48mm from a charge of 2.9 nC and a point at infinity?
4.The potential energy of an electron (q= -1.6 *10 -19C)INCREASES BY 3.3*10-15 J when it moves 3.5 cm parallel to a uniform electronic field.What is the magnitude of the electric field through wjich the electron passes?
5.A charge partice gains 3.1*10-12 f potential energy when it moves 4.7 cm through a uniform electric field.The potential difference across this distance is -73 V.
What is the magnitude of the electronic field?
6.A charge particle moves through a distance of 9.35m to a uniform electronic field.The electronical potential energy of the particle increases by 3.17*10-10J as it moves.The electric field has a magnitude of 1.25*10 (5)N/C.
