Problem 74

A semicircular loop of radius a carries positive charge Q distributed uniformly. Find the electric field at the loops center (point P in Fig. 20.34). (Hint: Divide the loop into charge elements dq as shown, write dq in terms of the angle then integrate over ) du, u. the gas in the engine has specific heat ratio find the enginesefficiency, assuming all processes are reversible. (b) Find themaximum temperature in terms of the minimum temperature(c) How does the efficiency compare with that of a Carnotengine operating between the same temperature extremes?
