Question
sapling earning A particle of charge q and mass m is moved through a distance d (from point A to point B) within a region of constant, uniform electric field as shown. Let the work done by the electric field during this motion be WE, and let the potential difference that the particle moves through be AV. Below, indicate how WE and AV change (or state that there is no change) as the other variables are changed Effect on We: Effect on AV Scenario Change: The magnitude of the field is doubled The sign of the charge is changed The direction of the field is reversed The mass of the particle is halved The particle moves from B to A instead of A to B The sign of the field's horizontal component is changed The magnitude of the charge is doubled no change doubled sign changed ca tell MapExplanation / Answer
the equation for workdone by the electric field is
W = Fs = Eqs
the relation between electric field and potential difference is
V = Ed
if the magnitude of filed is doubled , the workdone by the electric field is also doubled , the potential difference also doubled
if the sign of charge is changed , W_E sign changed, V no change
the direction of field is reversed , W_E sign changed , V sign changed
the mass of the particle is halved , W_E no cahnge, V no change
he particle move from b to a instead of a to b = sign changed
The sign of the fields horizontal component is changed = no change
The magnitude of the charge is doubled,W_E is doubled V, no change
