Two point charges q1 = +38 nC and q2 = -61 nC, are separated by a distance 34 cm. Find the magnitude of the electric force. Eg., 0.0001 can be written as 1.0e-4 or as 1.0E-4. Spaces not allowed. Round off your answer to two significant figures. DO NOT INCLUDE THE UNITS

Two charged spheres are 2 m apart from each other. The blue sphere has a charge of +498 µC and is attracting the red sphere with a force of 836 N. Find the charge of the red sphere in mC. How to answer: Round your final answer to 1 decimal place. Write 1.2 to represent the red charge has a positive charge OR -1.2 to represent it has a negative charge. Answer in mC.
