The PSBB Millennium School Geruhambakkam Chennai XII Physics Worksheet Electric charges and field 1. 1. An oil drop of 12 excess electrons is held stationary under a constant electric field of 2.55x104 v/m. The density of oil is 1.26 gm/cc. Estimate the radius of the drop.[Ans:1.428x10-6m] 2. Two small spheres each of mass 10-6kg are suspended from a point by silk threads 50 cm long. They are equally charged and repel to a distance of 20cm.Calculate

AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

Physics Moment of a force: Moment of a force = force x perpendicular distance of the line if action if the force from fulcrum Law of moments: When a body is in equilibrium the sum of the clockwise moments about any point equals the sum of the anticlockwise moments about the same point. Centre of mass: Centre of mass is the point where whole mass of the body assumes to be concentrated. II. If the vertical line through the centre of mass is outside the base it will be a topples but if it’s passed

UNSOLVED MYSTERIES Unsolved Mysteries - Beyond the standard model The Standard Model is nowhere near perfect. It may explain the six quarks‚ leptons‚ and four forces‚ but it is not complete. There are still questions about antimatter‚ dark matter‚ and the inability for the Standard Model to predict particle mass. There is no guarantee that quarks and leptons are actually fundamental. Lastly‚ scientists still don’t understand gravity’s role. Unsolved Mysteries - The standard model as a theory

Black Hole A Black hole is a place in space where the gravity is so strong that nothing can escape it pull. Cyclotron A type of particle accelerator that was created first in the 1930’s. It was made of two Dshaped cavities in a constant magnetic field. Dark Matter A form of matter that is not like ordinary

Quality of measurement Write Up Wire Wire This diagram shows how we carried out our experiment‚ by connecting 2 wires to the ohmmeter and attached the wires to the samples we used in our experiment. Preliminary Experiment At first in our preliminary experiment my group and me decided to use an ohmmeter instead of a multimeter. We did this as we thought it would make it easier for us to record our results. These are the results we got from our preliminary experiment: Length (mm)
