The integral xdr is to be evaluated up to 3 decimal places using Simpson's 3-point rule. If the interval [0, 1] is divided into 4 equal parts, the correct result is (a) 0.683 60. 59. (b) 0.667 (c) 0.657 (d) 0.638 In a classical model, a scalar (spin-0) meson consists of a quark and an antiquark bound by a poten-
