Two capacitors A and B are connected in
series across a 100V supply and it is
observed that the p. d. across them 60V and
40V respectively. A capacitor of 2uF
capacitance is now connected in parallel
with A and the p. d. across B rises to 90V.
Calculate the capacitance of A and B in
microfarads.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
