  In this paper, we discuss the impact of the following laboratory experiments
and astrophysical observation of neutron stars (NSs) on its equation of state
(EoS): (a) The new measurement of neutron skin thickness of $\rm ^{208} \! Pb$,
$R_{\rm skin}^{208} = 0.29 \pm 0.07$ fm by the PREX-II experiment. (b) The mass
measurement of PSR J0740+6620 has been slightly revised down by including
additional $\sim 1.5$ years of pulsar timing data. As well as the radius
measurement of PSR J0740+6620 by joint NICER/XMM-Newton collaboration which has
a similar size to PSR J0030+0451. We combine these information using Bayesian
statistics along with the previous LIGO/Virgo and NICER observations of NS
using a hybrid nuclear+piecewise polytrope (PP) EoS parameterization. Our
findings are as follows: (a). Adding PREX-II result yields the value of
empirical parameter $L = 69^{+21}_{-19}$ MeV, $R_{\rm skin}^{208} =
0.20_{-0.05}^{+0.05}$ fm, and radius of a $1.4 M_{\odot}$ ($R_{1.4}) =
12.75_{-0.54}^{+ 0.42}$ km at $1 \sigma$ confidence interval (CI). We find
these inferred values are mostly dominated by the combined astrophysical
observations as the measurement uncertainty in $R_{\rm skin}^{208}$ by PREX-II
is much broader. Also, a better measurement of $R_{\rm skin}^{208}$ might have
a little effect on the radius of low mass NSs, but for the high masses there
will be almost no effect. (b) After adding The revised mass and radius
measurement of PSR J0740+6620, we find the inferred radius of NSs is slightly
pushed towards the larger values and the uncertainty on the radius of a $2.08
M_{\odot}$ NS is moderately improved.
