A particle moves in a circle of radius $5 cm$ with constant speed and time period $0.2 π s$ . The acceleration of the particle isNEET 2011 (Screening)

Options:

Answer:

Solution:

Given, $r = 5 cm = 5 \times 1 0^{- 2} m$ and $T = 0.2 π s$ We know that acceleration $a = r ω^{2} = \frac{4 π ^{2}}{T ^{2}} r = \frac{4 \times π ^{2} \times 5 \times 1 0 ^{- 2}}{( 0.2 π ) ^{2}} = 5 ms^{- 2}$
