It's about (electric potential difference) I need answers for the 6 questions
In a Millikan's oil drop experiment, an oil drop of diameter 2.3x10-4 cm and density 1.7 g cm-3 is observed motionless between two oppositely charged plates separated by the distance 3 cm of potential difference 15 kV. Calculate the charge of the oil drop. FE E Oil droplet
An electron is accelerated through the potential difference of 45000 V as shown. The separation between the plates is 0.34 m. electric field lines tungsten target OV +45 000 V A X-rays cathode anode Select one or more: OA. The kinetic energy of electron is double at tungsten target than at anode. B. The electric potential energy of electron is the highest at anode C. The electric field at point A is 132352.94 N/C D. The electron is accelerated uniformly between the cathode and anode. OE. The kinetic energy of electron is the highest at anode. F. The electric field at point B is 132352.94 N/C G. The electric potential energy of electron is the highest at cathode H. The electron moves with an increasing velocity between anode and target.
An Electron is emitted by heating a cathode and is accelerated by the potential difference between the anode and a cathode. The electron emerges out from the anode with velocity 5.1x106 m/s. Find the velocity (in m/s) of the electron when it comes out of the parallel plates at a PD of 800 V. Use x = 0.16 m and y = 0.07 m. . 800 V Cathode Anode 10 leuw у electron beam Jov Give your answer in scientific representation rounded off to two decimal places. (Remember that 2.97x108 = 2.97E8 in moodle) Select one: O A. 5.106 O B. 6.31e7 O C.5.12 OD. 6.296 O E. 5.29e5 Clear my choice
A charge +3 e moves from an equipotential P to equipotential Q. The equipotential P and Q have an electric potential 11 kV and 3.1 kV respectively. Find the magnitude of the loss of electric potential energy (in keV) during this motion. Q P 1 1 0.2m Om 0.1m 0.3m Round off the answer to 2 decimal places. don't put any negative sign with the answer.
An Electron is emitted by heating a cathode and is accelerated by the potential difference of V volts between the anode and a cathode. The electron emerges out from the anode with velocity of 4 x 107 m/s. Find height h gained by the electron while leaving the parallel plates. Use x = 0.13 m and y = 0.04 m. 800 V Cathode Anode у leuw electron beam OOV х Answer:
A positive charge 1.2 nC is dragged from point B to A in a uniform electric field 1.9 x103 N/C as shown in the diagram. Farag TIHEITTT Fel Find the work done (in joules) to do so if the separation between points A and B is 28 mm. Give your answer in scientific representation rounded off to two decimal places.
