Is the force of gravity that attracts my body to the Earth related to the force of gravity between the planets and the Sun

Amagnetic field "does not" interact with stationary electric charges. so, a.hope my answer you : )

Did you ever figure out the right answers since you asked?

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Fb is the magnetic force  q is the chargev is the velocity of the charge  b is the magnetic field  the equation is: f=|q|vbsin0
