KLIK HIER OM VRAAG 6 TE SIEN VRAAG 6 6.1 'n 3 kg-trоllie is in rus оp 'n hоrisontаle wrywinglose oppervlаk. 'n Konstаnte horisontale krag van 10 N word op die trollie toegepas oor 'n afstand van 2,5 m. Wanneer die krag by punt P verwyder word, beweeg die trollie 'n afstand van 10 m teen die helling op totdat dit die maksimum hoogte by punt Q bereik. Terwyl die trollie teen die helling opbeweeg, is daar 'n konstante wrywingskrag van 2 N wat daarop inwerk. 6.1.1 Skryf die naam neer van 'n nie-konserwatiewe krag wat op die trollie inwerk en wat wel werk verrig op die trollie soos dit teen die helling opbeweeg. (1) 6.1.2 Stel die WERK-ENERGIE-STELLING in woorde. (2) 6.1.3 Gebruik die werk-energiestelling om die spoed van die trollie te bereken wanneer dit punt P bereik. (4) 6.1.4 Bereken die hoogte, h, wat die trollie by punt Q bereik. (5) 6.2 ’n Boer gebruik ’n 8 W-elektriese pomp om water uit ’n rivier te haal om sodoende die besproeiingskanale te vul wat die grond in sy landerye klam hou. Elke minuut lig die pomp 12 kg water teen 'n konstante tempo deur 'n vertikale hoogte van 3m. 6.2.1 Bereken die kraglewering van die motor. (4) 6.2.2 Bereken die persentasie doeltreffendheid van die motor. (2) [18]

At a point Q, a distance 3,1 x 108 m above the surface of Cybertron, the gravitational field strength is 1,9 N.kg-1. 7.1.1 Define a gravitational field. (2) 7.1.2 A comet of mass 5,85 x 1012 kg passes Cybertron. Calculate the magnitude of the gravitational force experienced by the comet when it is at point Q. (3) 7.1.3 Calculate the mass of the Cybertron. (4) 7.2 Two small spheres, X and Y, carrying charges of +6 x 10-6 C and +8 x 10-6 C respectively, are placed 0,20 m apart in air. 7.2.1 State Coulomb's law in words. (2) 7.1.2 Calculate the magnitude of the electrostatic force experienced by charged sphere X. (4) A third sphere, Z, of unknown negative charge, is now placed at a distance of 0,30 m below sphere Y, in such a way that the line joining the charged spheres X and Y is perpendicular to the line joining the charged spheres Y and Z, as shown in the diagram below. All three charges lie flat on the plane of the page. 7.2.3 Draw a labelled vector diagram showing the directions of the electrostatic forces and the net force experienced by charged sphere Y due to the presence of charged spheres X and Z respectively. (Be sure to include arrows on all the forces.) (3) 7.2.4 The magnitude of the net electrostatic force experienced by charged sphere Y is 15,20 N. Calculate the charge on sphere Z. (4) [22]
