The correct answer is the thumb of the right hand.
Explanation:
The Force will follow Lorentz's law, a vectorial product: F= q*v x B, where:
q is the charge of the particle.
v is its velocity.
x indicates the vector product.
B is the magnetic field.
Being a vector product F the plane formed by v and B will be perpendicular. To determine the sense we will apply the variant of the rule of the right hand. The fingers of the right hand without the thumb run from vector v to vector B, so in this case, the force will have a sense upwards. It must be said that the rule always indicates the direction of the positive charge if the charge is negative the direction of F is inverse (downwards).
Answer: During sexual reproduction, the genetic material of two individuals is combined to produce genetically-diverse offspring that differ from their parents. The genetic diversity of sexually-produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment
The gravitational force is inversely proportional to the square of the distance between their centers. So the force is greatest when the distance is zero.
