Answer:
La velocidad del haz de electrones es 1.78x10⁵ m/s. Este valor se obtuvo asumiendo que el campo magnético dado (3500007) estaba en tesla y que la fuerza venía dada en nN.
Explanation:
Podemos encontrar la velocidad del haz de electrones usando la Ley de Lorentz:
(1)
En donde:
F: es la fuerza magnética = 100 nN
q: es el módulo de la carga del electron = 1.6x10⁻¹⁹ C
v: es la velocidad del haz de electrones =?
B: es el campo magnético = 3500007 T
θ: es el ángulo entre el vector velocidad y el campo magnético = 90°
Introduciendo los valores en la ecuación (1) y resolviendo para "v" tenemos:
Este valor se calculó asumiendo que el campo magnético está dado en tesla (no tiene unidades en el enunciado). De igual manera se asumió que la fuerza indicada viene dada en nN.
Entonces, la velocidad del haz de electrones es 1.78x10⁵ m/s.

Answer:
Isolated or Closed system, both are correct
B: an increase in acceleration caused an increase in force.
This is based on the concept of force on an object.
Now, formula for force is commonly known as;
Force = mass × acceleration
Now, mass and acceleration are the input values that make the output which is the Force to either increase or decrease.
- Now, for the line of dominoes to fall, it means that the force was so overwhelming that the dominoes couldn't resist it.
Now, this output which is the force became so much as a result of the increase in acceleration of the motion that triggered its movement.
Moreover, the force is directly proportional to the acceleration!
Thus, we can say that an increase in acceleration caused an increase in force.

Explanation: The formulae for intensity of an electric field of a solid metal sphere relative to a point is given below
r
where 
, 
, r = 0.1m r = is the position vector of the charge.
it has been stated in the question that the charge is placed at the center thus it has no position vector.
