21.解:(1)将点P横坐标xP=2代人x2=2py中,得∴P(2.2)则OP=p+4,又点P到准线的距离为d=多+(2分)则2+(2)=1+(号+2)解得p2=4,抛物线C的方程为x2=4(4分)(2)抛物线x2=4y的焦点为F(0,1),准线方程为yH(0,-1)设A(x,y),B(x2,y),直线AB的方程为y=kx代入抛物线C的方程得x2-4kx-4=0,A>0∴x1+x2=4k,x1x2=-4,①(6分)由AB⊥HB,得kA·khB=-1,又kA=k1y2+1∴(y1-1)(y2+1)+x1x2=0(8分)即(1-1)(+1)+n=0+1(-)=1+=0②把①代入②得,x2-x2=16(10分)则|AF|-|BF|=y+1-y216=4(12分)
