By the looks of things you need to refer to your child panel by it's 'id' which I guess is 'p' from your code above.

So you'd want something like this:

function: onbtnClick(show) {

    var childPanel = Ext.getCmp('p');
    if(show) {
        childPanel.show();
    } else {
        childPanel.hide();
    }
}
