"Input \\space voltage=460V"
"Speed(N) =500rpm\\implies \\newline\\omega=2\\pi N\/60=52.36 \\space rad\/sec"

"Total \\space resistance\\space of armature \\space and \\space field=\\newline Rse+Ra=0.6\\Omega"
"We \\space have, \nV=Eb+Ia(Ra+Rse) \\newline\nHence , Back \\space emf (Eb) =460-40\\times0.6=436V"
"We \\space have, \\newline \nEbIa=T\\omega\\implies\\newline Torque(T) \\newline=EbIa\/\\omega=436\\times40\/52.36= 333.08Nm"
