False: The most common salt found in ocean water would be sodium chloride. Seawater or ocean water contains many types of salt and the most abundant type of dissolved ions are sodium and chloride ions which when crystallized becomes NaCl.
Answer:
The correct option is 'c': The Force vector (F) and the magnetic field vector (B) are always perpendicular.
Explanation:
The magnetic force that acts on a charged particle moving in a magnetic field is given by

As we can see that vector cross product is involved hence we conclude that Force vector (F) is always perpendicular to both the velocity vector (v) and the magnetic field vector (B) which may be at any angle with respect to each other.
Hence we conclude that vectors F and B are always perpendicular.
The average acceleration is 5/4 = 1.2m/s ^2
Hope I can get brainliest answer :)
