5. ### An electric charge of 2.10-3C at a point X in an electric field had electric potential energy of 4.10-2 J. It was moved to another point YÂ ?

Î”EPE = 0.0610J - 0.0410J = 0.0200 J, so a) Î”Vxy = 0.0200J / 2.10e-3C = 9.52 V b) E = Î”Vxy / d = 9.52V / 0.25m = 38.1 V/m assuming the motion was parallel to the field.

7. ### Does anyone know how to do this physics question?

We know Ï‰ = 5.4 = âˆš(k/m) and Ï‰ = 2Ï€f = 2Ï€/T so T = 2Ï€/5.4 A = 0.1 Vmax = Ï‰A = 5.4*0.1 = 0.54 We don't know k or m, just their ratio: 5.4Â² = k/m A. and D.
