A second identical block, with twice the mass and twice the surface area as the original block is placed on the same horizontal board with the original block. One end of the level board is now slowly raised. Which block, if any, is the first to slip and begin to slide down the board? Justify your answer. Equations may be part of your reasoning, but equations alone are not sufficient justification.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
