Under Section 41(2)(a), rules made by the Central Government may provide for the period of notice to be given by the Central Government to terminate the appointment of:

Section 41(2)(a) empowers rule-making SPECIFICALLY for the notice period applicable to terminating a PART-TIME (non-Government-servant) member's appointment under clause (b) of the proviso to Section 5(1) - notably, the WHOLE-TIME (non-Government-servant) member's termination notice period under clause (a) of that same proviso is already fixed directly in the Act itself (a minimum of three months, or salary in lieu), requiring NO separate rule-making at all, and clause (c) (Government-servant members) permits termination 'at any time' with no notice period to prescribe. This selective rule-making delegation - covering only the part-time-member notice period, since the whole-time period is hard-coded and the Government-servant termination is notice-free - is a subtle, cross-referencing point testing precise recall of Section 5(1)'s proviso structure.
