An Electron Has a Velocity of 6

question 3

Multiple Choice

An electron has a velocity of 6.0 × 106 m/s in the positive x direction at a point where the magnetic field has the components Bx = 3.0 T, By = 1.5 T, and Bz = 2.0 T. What is the magnitude of the acceleration of the electron at this point?

• A)2.1 × 1018 m/s²
• B)1.6 × 1018 m/s²
• C)2.6 × 1018 m/s²
• D)3.2 × 1018 m/s²
• E)3.7 × 1018 m/s²

Definitions:

Deactivator

A chemical compound or group that decreases the reactivity of an atom or a formation within a molecule, often used in reference to aromatic substitution reactions.

O,p-director

A term describing substituents on an aromatic ring that direct incoming substituents to the ortho and para positions in electrophilic aromatic substitution reactions.

Strongest Activating Group

A substituent that increases the reactivity of an aromatic ring toward electrophilic aromatic substitution reactions the most.

Electrophilic Aromatic Substitution

A reaction where an electrophile replaces a hydrogen atom in an aromatic ring, a common mechanism in aromatic chemistry.
