The magnetic force experienced by a proton moving with a speed of 3 ×
m/s in the magnetic field B of magnitude 6 ×
T will be 2.88×
N.
Magnetic force can be defined as the attraction or repulsion force that arises between electrically charged particles due to the motion of the charged particles.
Given,
Speed = 3×
m/s
Magnetic Field, B= 6 ×
T
Magnetic force is the product of velocity, the charge of a proton, and the magnetic field present there.
The magnetic force can be represented as:
F=qvB
F=1.6×
×3×
×6 ×
F=2.88×
N
Hence, the magnetic force experienced by the proton will be 2.88×
N.

Answer:
The answer to your question is 159.0 grams
Explanation:
data
mass of K₂O = ?
mass of K = 132 g
Process
1.- Balance the chemical reaction
Chemical reaction
K(s) + O₂ ⇒ K₂O
Reactants Elements Products
1 K 2
2 O 1
This reaction is unbalanced
4K(s) + O₂ ⇒ 2K₂O
Reactants Elements Products
4 K 4
2 O 2
Now the reaction is balanced
2.- Calculate the mass of K₂O
Atomic mass of K = 39 x 4 = 156 g
Molar mass of K₂O = 2[(39 x 2) + 16] = 188 g
156 g of K ------------------ 188 g of K₂O
132 g of K ----------------- x
x = (132 x 188) / 156
x = 159.0 grams
