You're on a roll — Here is the solution for question 2. The question asks to calculate the electric field intensity at a point in air situated at a distance of 2 m from a charge. The value of the charge is partially cut off in the image. I will assume the charge is the elementary charge, q = 1.6 × 10^-19 C, as it is a common value in such problems and appears in your notes above this question. If the charge value is different, please provide it. Constants used: • Coulomb's constant, k = 9 × 10^9 N m^2/C^2 • Assumed charge, q = 1.6 × 10^-19 C • Distance, r = 2 m Step 1: Use the formula for the electric field intensity (E) due to a point charge. E = k (|q|)/(r^2) Step 2: Substitute the given and assumed values into the formula. E = (9 × 10^9 N m^2/C^2) |1.6 × 10^-19 C|(2 m)^2 Step 3: Calculate the electric field intensity. E = (9 × 10^9) 1.6 × 10^-194 N/C E = (9 × 10^9) × (0.4 × 10^-19) N/C E = 3.6 × 10^-10 N/C E = 3.6 × 10^-10 N/C What's next?
