The equation of motion of a one-dimensional forced harmonic oscillator in the presence of a dissipative force is described by +16x=6te +4te". The general form of the dx dt dx dt particular solution, in terms of constants A, B etc., is (a) t(At + Bt+C)e +(Dt +E) e (c) 1 (At + Bt+C)e +1(Dt+E) e +10. -8r (b) (At + Bt+C)e +(Dt + E)e- (d) (At + Bt+C)e +t(Dt+E)e*
