- An electron is orbiting a nucleus which has a charge of 14e, under the action of the Coulomb force at a radius of 1.14 × 10-¹0 m. Calculate the angular velocity of the electron, in radians per second. @=||The electric field associated with an alpha particle at a point 7.5x10-3m from the alpha particle is ?Now you have a nucleus with 19 protons at x = 7.9 Angstroms on the x-axis. How much work would it take to bring in ANOTHER nucleus with 16 protons from 1 m away and place it at y = 4.8 Angstroms on the y-axis? -47.9 eV 473.0 eV 340.1 eV 425.1 eV
- At the points of the angles of an equilateral triangle with a side length of 30 cm, the electric charges are 2uC, 2 uC, and 3uC, respectively. What is the coulomb force experienced by a 3uC charge? (with pictures) PLEASE HELP SIR, STEP BY STEP, WITH PICTURE, THX.Robert Millikan was an American physicist who in 1909 performed a classic experiment involving charged oil drops. Millikan adjusted the voltage applied between two metal plates in order to suspend charged drops in the resulting electric field. For a suspended drop, the electrostatic force directed up exactly balances out the weight of the drop. Millikan ultimately determined the charge on an electron and that charge is quantized. This means that charge comes in increments, discrete amounts, rather than any amount.A NEGATIVELY-charged oil drop is suspended between two plates of opposite charge by an electric field of 603 newtons per coulomb. The drop is determined to have a mass of 8.86 x 10-17 kilograms.a. What is the charge on the drop? Include units in your answer. More information.b. How many excess electrons does it carry? Hint: Charge is quantized, so this answer must be just an integer.Now you have a nucleus with 15 protons at x = 7.3 Angstroms on the x-axis. How much work would it take to bring in ANOTHER nucleus with 12 protons from 1 m away and place it at y = 3.0 Angstroms on the y-axis? 189.4 eV 270.5 eV -57.5 eV 328.1 eV
