563 × 10^-¹² m from the plutonium nucleus?

Question

Quizplus · Accepted Answer

The given expression represents the distance between a point and a nucleus, where S1, U1, and P1 represent the directions of the x, y, and z axes respectively. The distance from the nucleus is equal to the square root of the sum of the squares of the coefficients multiplied by the corresponding unit vectors. 
Calculating this expression, we get: 
(563^2 + 112^2 + 2^2)^1/2 = 6.83 × 10^12 m
Therefore, the answer is choice C.
