Two identical small spheres of mass 2.94 g each carry equal charge (sign and magnitude) and are placed 3.36 cm apart. When released, each sphere experiences an instantaneous acceleration of 481 m/s². Determine the magnitude of the charge on one of the spheres. Report your answer in nC.(1nC=1.00×10⁻⁹ C and k=8.99×10 9 Nm²/C²)
