$\begin{gathered}
  \,\,\,\,\,\,\,\,\,\,\,\,\,\,Here,\,m = 10\,g\, = {10^{ - 2}}\,kg, \hfill \
  R = 6.4\,cm = 6.4 	imes {10^{ - 2}}m,\,{K_f} = 8 	imes {10^{ - 4}}\,J, \hfill \
  {K_i} = 0,\,{a_{t = }}? \hfill \
  {	ext{Using}}\,work\,energy\,theorem, \hfill \
  Work\,done\,by\,all\,the\,forces = Change\,in\,KE \hfill \
  {W_{	an gential\,force\,}} + {W_{centripetal\,force}} = {K_f} - {K_i} \hfill \
   \Rightarrow {a_t} = \frac{{{K_f}}}{{4\pi Rm}} = \frac{{8 	imes {{10}^{ - 4}}}}{{4 	imes \frac{{22}}{7} 	imes 6.4 	imes {{10}^{ - 2}} 	imes {{10}^{ - 2}}}} \hfill \
  \,\,\,\,\,\,\,\,\,\,\,\, = 0.099 \approx 0.1\,m\,{s^{ - 2}} \hfill \ 
\end{gathered} $
