Why was the negative plate earthed in milikans oil drop experiment ? |
|
Answer» Answer: In Millikan's oil DROP experiment, the motion of oil drop is due to gravitational force and then the motion is due to electric field. In the first case, when the oil drop moves downwards due to gravitational force, the viscous force acts in UPWARD direction opposing its motion. When the electric field is switched on, and if the upper plate is positively charged and the lower plate is negatively charged(equivalently electric field is downwards), the oil drop will move upward, ASSUMING the charge of oil drop to be NEGATIVE. The VOLTAGE was adjusted until the drops were suspended in mechanical equilibrium, indicating that the electrical force and the gravitational force were balanced. Now using the known electric field, Millikan and Fletcher could determine the charge on the oil droplet. |

What is the value of tangential acceleration in U.C.M.? iii. The surface tension of water at 0℃ is 75.5 dyne/cm. Find surface tension of water at 25℃. [ for water = 0.0021/℃] |
|
Answer» In uniform circular motion (U.C.M), It's angular VALOCITY is constant. a = dw/dt. but, w = constant. ∴ a = 0. Thus, the value of TANGENTIAL acceleration in uniform circular motion is zero. t 1 = 0⁰C t 2 = 25⁰C α = 0.0027/⁰C T = T0 (1 – α∆t) = T0 [1 – α (t2 – T1 )] T = T0 [1 – α (t2 – t1 )] T = 70 [1 – 0.0027 (25 – 0)] = 70 [1 – 0.0027 × 25] = 70 × 0.9325 ∴ T = 65.275 dyne/cm please mark me brain mark list |

What are the main purpose of milikans oil drop experiment? |
|
Answer» In 1909, Robert Millikan and Harvey FLETCHER CONDUCTED the oil drop experiment to determine the charge of an electron. They suspended tiny CHARGED droplets of oil between two metal electrodes by balancing downward gravitational force with upward drag and electric forces. pls MARK me as brainliest❤❤ |

Consider the unit vectoras i for positive x-direction and ) for positive y direction. Now the rain is falling vertically with a speed of 30m/s-ve y direction). A woman on a biexcle is travelling with a speed of 10 m/s in the East-West direction(-ve x direction). Now she has to hold her umbrella to protect herself. So if we can get the velocity of rain relative to the travelling woman(relative velocity), according to its opposite direction she will open her umbrella. N-W N N-E S-E S-W determine the vector representation of relative velocity of rain due to woman |
