point charges are q₁=8 μC, q₂=-7 μC Find the electric field due to these charges at the origin: (o)

(q1)<------10cm------o----------10cm---------->(q2)

Expert Solution

(q1)A<---------10cm------O----------10cm---------->B(q2)

8 μC------------------------>--------------------------->-7 μC

E1 E2

Distance between the two charges , AB=20 cm

Let net elctric field at O is Eo

Magnitude of electric field at point O caused by q1=8 μC charge,

where, ε0=Permittivity of free space and

Magnitude of electric field at point O cause by q2= - 7 μC charge,

in diagram you can see that direction of electric field intensities are in the same direction

Hence, electric field at the midpoint O of the line AB joining the charges is 13.5 × 10⁶ N/C along OB
