You should be able to use the #states property on your field to do what you are asking. You can add multiple validations and it will create all the jquery for you.

eg:

// Show the email field when email selected for radiofld
$form['email'] = array(
  '#type' => 'textfield',
  '#title' => t('Email'),
  '#states' => array(
    'visible' => array(
      array(
        ':input[name="radiofld"]' => array('value' => 'email'),
      ),
    ),
  ),
);

// Show error message for phone field
$form['phoneerr'] = array(
    '#type' => 'markup',
    '#markup' => 'No Phone selected',
  '#states' => array(
    'visible' => array(
      array(
        ':input[name="radiofld"]' => array('value' => 'email'),
      ),
    ),
  ),
);  

// Show the phone field when phone selected for radiofld
$form['phone'] = array(
  '#type' => 'textfield',
  '#title' => t('Phone'),
  '#states' => array(
    'visible' => array(
      array(
        ':input[name="radiofld"]' => array('value' => 'phone'),
      ),
    ),
  ),
);

// Show error message for email field
$form['emailerr'] = array(
    '#type' => 'markup',
    '#markup' => 'No Email selected',
  '#states' => array(
    'visible' => array(
      array(
        ':input[name="radiofld"]' => array('value' => 'phone'),
      ),
    ),
  ),
);

if you really insist on using jquery independently then you should put it in a function and call it with an onclick/onchange attribute:

$form['wayToContact'] = array(
       '#type' => 'radios',
       '#validated' => TRUE,
       '#title' => t('Best way to contact'),
       '#default_value' => 'Email',
       '#options' => array('Email' => $this->t('Email'), 'Phone' => $this->t('Phone')),
       '#attributes' => array(
            'class' => array('required')
            'onchange' => 'yourFunction(this)',
            'onclick' => 'yourFunction(this)'
       )
     );
