Write an assignment statement to calculate the nth term in an arithmetic sequence. The formula for calculating the value, v, of the nth term is v = a + (n-l)d , where a = the first number in the sequence and d = the difference between any two numbers in the sequence. 8. Coulomb's law states that the force F acting between two electrically charged spheres is given by the formula F = k q_l q₂/ r, where q_l is the charge on the first sphere, q₂ is the charge on the second sphere, r is the distance between the centers of the two spheres, and k is a proportionality constant. Write an assignment statement to calculate the force F.
