Verify that for the constant-angular-momentum flow of Fig. 14.1b, with v = j x/ 2 , two neighboring fluid elements move around each other

Verify that for the constant-angular-momentum flow of Fig. 14.1b, with v = j × x/ω̅², two neighboring fluid elements move around each other with angular velocity +j/ω̅² when separated tangentially and −j/ω̅² when separated radially.
