You put a test charge of 2e near two other particles. Particle A has a charge of -2e and is 0.02 m north of the test charge. Particle B has a charge of 3e and is 0.02 m east of the test charge. The magnitude of the net electrostatic force on the test charge in Newtons is:

The dissociation energy of a molecule is the energy required tobreak apart the molecule into its separate atoms. the dissociationenergy for a particular molecule is 5.48 x 10-18 j.suppose that this energy is provided by a single photon. determinethe (a) wavelength and (b) frequency of the photon
