An 100 V/m electric field is directed along the x axis. If the potential at the origin is 300 V, what is potential at the point ( -2m, 0) point

100 V

Explanation:

Electric field E = 100 V/m

Potential at the origin = 300 V

Potential at point (-2m, 0) i.e 2 m behind the origin = ?

From the equation ΔV = EΔd,

ΔV =

where is the potential at origin,

and is the potential at point (-2, 0)

E = electric field

Δd = 0 - (-2) = 2 m

= 300 -

equating, we have

 300 - = 100 x 2

300 - = 200

= 100 V

explanation:

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
