Abstract : This analysis reports a systematic study of AGN feedback in the galaxy cluster RXCJ0352.9+1941 using {\it Chandra} and own GMRT observations. Our temperature, as well as a cooling time profile, shows RXCJ0352.9+1941 is a weak cool-core cluster. The X-ray morphology shows two non-uniform extended sub-structures situated towards the North and South direction from the centre of the cluster. They emit most of their energy in mid energy band (1-2\,keV) and having temperatures $2.03\pm0.08$ keV and $2.31\pm0.09$ keV respectively. We detect a couple of X-ray cavities within $r\sim29$ kpc formed by the radio lobe arising from the central radio source and filled with 1.4 GHz radio plasma. The estimated average buoyancy age, total work done by the AGN and total cavity power are $t \sim 3.50\times10^7$ years, $3.20\times 10^{59} \ \rm{erg}$, and $P_{cav} \sim 3.1 \times 10^{44} \ \rm{erg \ s^{-1}}$, respectively. The cavity power suggesting that there is enough enthalpy associated with the cavity network to offset the radiative losses and effectively quench the cooling flow. Furthermore, in RXCJ0352.9+1941 we detect two cold fronts, one is along the South direction at $\sim$ 40\arcsec\ (79 kpc), while another is along East direction at $\sim$ 90\arcsec (179 kpc).
