Answer:

2.8 × 10^-11 C

Explanation:

The computation of the magnitude of q is shown below;

The electric field at point P because of point charge Q is provided by,

E = 8.6 × 10^-2 N/C

And, the separation between charge Q and P is r = 1.7m

Now According to the Coulomb's law,

E = kQ ÷ r²

8.6 × 10^-2 = 9 × 10^9 × Q ÷ (1.7)²

8.6 × 10^-2 × 2.89 ÷ 9 × 10^9 = Q

Q = (8.6 × 2.89 ÷ 9) × 10^-11

Q = 2.76 × 10^-11 C

= 2.8 × 10^-11 C
