I will rate the correct answers.

Four point charges are arranged as shown below, each a distance d from the center of the configuration. The value of the constant q is positive. Let blue arrows (top or right in each picture) represent electric fields and red arrows (bottom or left) represent forces. For each charge, pick the picture that best represents the directions of both the net force on the charge and the electric field at the charge due to the other three charges.

Solution

Here ,

for the electric field and force on the charges

for charge A

electric field ---> to the left

electric force ---> to the right

for the charge B

electric field ---> upwards

electric force ---> upwards

for charge C

electric field ---> to the right

electric force ---> to the left

for charge D

electric field ---> downwards

electric force ---> downwards
