3 Formula 1 point A positively charged point particle creates an electric field around it. At a distance of 3.502 m from the particle, the electric field due to its charge has magnitude \( 6.8 \times 10^{3} \mathrm{~N} / \mathrm{C} \). Find the magnitude of charge on the particle in units of Coulombs, assuming that the Coulomb's Law constant is \( \mathrm{k}=9.00 \times 10^{9} \mathrm{NC}^{-2} \mathrm{~m}^{2} \). Please enter your answer using scientific notation that is correct to exactly 3 significant figures (as in, for example, \( 6.34^{*} 10^{\wedge}-6 \) ).

A child pulls a wagon with a force of 16 pounds. The handle of the wagon makes an angle of \( 60^{\circ} \) with the ground. Express the force vector \( F \) in terms of \( i \) and \( j \). \( F=(\square) i+(\square j \) (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)
