We need to charge a metal sphere positively without touching it. This can be achieved using electrostatic induction.
Explanation:
Below is an attachment containing the solution.
Answer:
F = 147,78*10⁻⁹ [N]
Explanation:
By symmetry the Fy components of the forces acting on charge in point x = 0,7 m canceled each other, and the total force will be twice Fx ( Fx is x axis component of one of the forces .
The angle β ( angle between the line running through one of the charges in y axis and the charge in x axis) is
tan β = 0,5/0,7
tan β = 0,7142 then β = arctan 0,7142 ⇒ β = 35 ⁰
cos β = 0,81
d = √ (0,5)² + (0,7)² d1stance between charges
d = √0,25 + 0,49
d = √0,74 m
d = 0,86 m
Now Foce between two charges is:
F = K* q₁*q₂/ d² (1)
Where K = 9*10⁹ N*m²/C²
q₁ = 2,5* 10⁻⁹C
q₂ = 3,0*10⁻⁹C
d² = 0,74 m²
Plugging these values in (1)
F = 9*10⁹* 2,5* 10⁻⁹*3,0*10⁻⁹ / 0,74 [N*m²/C²]*C*C/m²
F = 91,21 * 10⁻⁹ [N]
And Fx = F*cos β
Fx = 91,21 * 10⁻⁹ *0,81
Fx =73,89*10⁻⁹ [N]
Then total force acting on charge located at x = 0,7 m is:
F = 2* Fx
F = 2*73,89*10⁻⁹ [N]
F = 147,78*10⁻⁹ [N]
Kinetic energy is a form of energy that an object or particle has by reaction of its motion.
Answer:
Explanation:
For reduction
Execution time = (instructions * CPI)/(Clock rate)
Since CPI is increased by 18%
18/100 +1 = 1.18
Therefore
P1 CPI = CPI x 1.18
P2 CPI = CPIx 1.18
P3 CPI = CPI x 1.18
Since clockrate reduces by 30% we have it to be a 0.7
P1: (Instructions x P1CPI) / 0.7
P2: (Instructionsx P2CPI) / 0.7
P3: (Instructions x P2CPI) /0 .7
