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.
What is the chargeon the particle?
