  7. V(t) = V(0)*[1-e^(t/RC)], we have 8 = 12 *[1 - e^(-1/RC)] or 0.6667 = 1 - e^(-1/RC) or e^(-1/RC) = 0.3334 or -1/RC = ln{0.3334) = -1.0996 or RC = 0.910 or C = 0.910/12000 = 27.78 microfarad

  9. ans e) 3200 N/m reason : it is bcoz,potential energy of a spring=1/2. k .x^2 for first spring, k =800 N/m , x= 12 cm for second spring, k =? , x=6 cm equating & solving the equation,we get 3200 N/m ans.
