Explanation / Answer

Here,

for the electric field due to a semicircular charge is given as

E = 2 k * Q/(pi * R^2)

as q = 12.7 pC

R = 7.72 cm = 0.0772 m

electric field due to both semicircular charges will be in same direction i.e - y direction and it will be equal in magnitude

for the net electric field

net electric field = 2 * 2 k * Q/(pi * R^2)

net electric field = 4 * 9 *10^9 * 12.7 *10^-12/(pi * 0.0772^2)

net electric field = 2.44 *10^1 N/C

the net electric field at the centre is 2.44 *10^1 N/C
