Final answer:
The value of the charge can be found using the equation q = F/E, where q is the charge, F is the electric force, and E is the electric field strength.
Step-by-step explanation:
The electric force on a charge in an electric field is given by the equation F = qE, where F is the force, q is the charge, and E is the electric field strength. In this case, the electric force is 3.7×10-2 N and the electric field intensity is 54 N/C. To find the value of the charge, we can rearrange the formula as q = F/E.
Substituting the given values, we have q = 3.7×10-2 N / 54 N/C = 6.85×10-4 C.
