Calculate the force on a +ve charge +2q at the centroid of the triangle. 2. Force acting on a charged particle kept between the pair of plates‚ having equal and opposite charge‚ is F. If one of the plates is removed‚ find the force acting on the same particle. 3. The plates of a parallel plate

Joseph John Thomson was born on December 18‚ 1856 near Manchester‚ England. His father died when J.J. was only sixteen. Thomson attended Owens College in Manchester‚ where his professor of mathematics encouraged him to apply for a scholarship at Trinity College‚ one of the most prestigious of the colleges at Cambridge University. Thomson won the scholarship‚ and in 1880 finished second in his class in the grueling graduation examination in mathematics. Trinity gave him a fellowship and he stayed

or push it away? The best explanation to this question involves the introduction of the concept of electric field. Action-at-a-distance forces are sometimes referred to as field forces. The concept of a field force is utilized by scientists to explain this rather unusual force phenomenon that occurs in the absence of physical contact. While all masses attract when held some distance apart‚ charges can either repel or attract when held some distance apart. An alternative to describing this action-at-a-distance

SAMPLE PROBLEMS: 112- Topic 1: ELECTRIC FORCES & ELECTRIC FIELDS. 1) Charges of - 6 and + 4 nC are 3 m apart. Determine the force they exert on each other‚ and the electric field at a point midway between them. |Solution: This is an electrostatics problem (stationary charges). Since the charges|[pic] | |are of opposite sign‚ they will attract each other. The forces are indicated in the|

Model of the Atom 1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2. The apparatus was in an evacuated
