A bacterial infection in an internal wound grows as N'(t) = N 0 exp(t), where the time t is in hours. A does of antibiotic, taken orally, needs 1 hour to reach the wound. Once it reaches there, the bacterial population goes down as dt dN = – 5N 2 . What will be the plot of N N 0 vs. t after 1 hour ?

1. N N 0 t(h)
2. N N 0 t(h)
3. N N 0 t(h)
4. N N 0 t(h) CAREER POINT CAREER POINT , CP Tower, IPIA, Road No.1, Kota (Raj.), : 0744-6630500 | www.ecareerpoint.com Email: info@cpil.in Page # 5 JEE Main Online
