Q1. An infinite non conducting sheet has a surface charge density σ = +5.80 pC/m2. (a) How much work is completed by electric field because of the sheet if a particle of charge q = +1.60 × 10-19 C is moved from the sheet to a point P at distance d = 3.56 cm from the sheet?(b) If the electric potential V is defined to be zero on the sheet , what is V at P.
Q2. A 1000 kg steel beam is supported by the two ropes. Each rope can support a maximum sustained tension of 5700 N. Will the ropes break?
Does the rope break?
