Isn’t it a bowling ball cause it’s the heaviest so it likely to go faster and hit the ground .
B compressed 2.17 cm from equilibrium. Answer in units of j
Answer:
a) No, Two vectors with different magnitudes can never add up to zero.
b) Yes, Three or more vectors with different magnitudes can add up to zero.
Explanation:
a) No, Two vectors with different magnitudes can never add up to zero.
Given vector A and B
A = (x1,y1,z1) and B = (x2,y2,z2)
For A + B = 0
This conditions must be satisfied.
x1 + x2 = 0
y1 + y2 = 0
z1 + z2 = 0
Therefore, for those conditions to be meet the magnitude of A must be equal to that of B.
b) Yes, Three or more vectors with different magnitudes can add up to zero.
For example, three forces acting at equilibrium like supporting the weight of a person with two different ropes.
W = T1 + T2
Where;
W = Weight
T1 = tension of wire 1
T2 = tension of wire 2
Answer:

0.000439077936334 m
Explanation:
q = Charge of electron = 
E = Electric field = 
= Permittivity of free space = 
d = Distance between plates = 2 cm (assumed)
m = Mass of electron = 
The beam consists of electrons which means it has negative charge this means the upper plates will be positive and the lower plate will be negative.
The direction is upper to lower lower plate.
= Permittivity of free space = 
Electric flux is given by

The charge per unit area on the plates is 
Deflection is given by

The deflection is 0.000439077936334 m
