Mismatch Between Father's First And Middle Name

it will not create any problem if the department wants then you can give an affidavit otherwise there is no any requirement as the name is same

1. since the names are the same, however, the only difference is space between UMA & NATH, therefore, it won't make any difference/hassles. 2. the concern organization may ask you to submit a duly sworn affidavit in this regard,

There will be no problem as such. You may file a duly sworn and attested Affidavit to the effect that it is a name of a same person and/or Your Father is also known as alias this name it will resolve the matter. Please give me Rank Five and follow me after reviewing my resume and book a consultation for further discussion and explanation if required.
