1. Three 1.0uf capacitor are (a) connected in series to a 2.0v battery (b) connectd parallel with each other and 2.0v battery, cal the charge on each of the capacitors in each a&b
2. Cal the electrostatic force between two alpha particles when 3.2 x 10^-12c also if the mass of each particle is 6.68 x 10^-27. Cal the gravitational force between the two particles.Compare the magnitude of the calculated force using electrical constant value of 9 x 10^7 nmc and gravitational constant of 6.67 x 10^11.
3. A charge of 1.6 x 10^-19c enters a magnetic field of flux density 2.0w/m^ with a velocity of 2.5 x 10^7m/s. Cal the force on the charge with an angle of 30"
4.cal the force on a cable of length 200m carrying a current of 200A in a direction of N30"E at a place where the horizontal component of the cable magnetic field is 10^-5
thanks in advance
