A 2.0 g metal cube and a 4-0 g metal cube are 6.0 cm apart. 2.0 g cube measured between their centers, on a horizontal surface. For both, the coefficient of static friction is 0.65. Both cubes. neither of them moves initially neutral, are charged at a rate of 4.5 nC/s. 4.0 g cube both cubes start to move at the same time My Answers Give Up Submit Correct Part B How long after charging begins does one cube begin to slide away?

here ,
let the time taken is t
when the 2 g cube starts to move
electrical force = frictional force on cube
9 *10^9 * (4.5 *10^-9 * t)^2/(0.06)^2 = 0.002 * 9.8 * 0.65
solving for t
t = 15.9 s
it will start to move at 15.9 s
