In an experiment to determine the speed and position of an electron (m = 9.11 × 10^-³¹ kg),three researchers claim to have measured the position of the electron to within ± 10^-⁹ m.They reported the following values for the speed of the electron: Which of these measurements violates one or more basic laws of modern physics? A)A only B)B only C)A and B D)B and C E)A,B,and C

Option A violates the Heisenberg uncertainty principle which states that it is impossible to determine both the position and momentum of a particle with absolute precision. The product of the uncertainties in position and momentum must be greater than or equal to Planck's constant.

Option B violates the speed limit given by Einstein's theory of relativity, which states that no object can travel faster than the speed of light in a vacuum.

Option C violates both the uncertainty principle and the speed limit given by Einstein's theory of relativity. Therefore, option C is the correct answer.
