A particle of mass 1 g executes an oscillatory motion on the concave surface of a spherical dish of radius 2m placed on a horizontal plane, Figure . If the motion of the particle begins from a point on the disc at a height of 1 cm. from the horizontal plane and coefficient of friction is 0.01 , find the total distance covered by the particle before coming to rest.

Options

A. 2 m
B. 10 m
C. 1 m
D. 20 m

Answer

C

Explanation

(c ) Then,
`mu` mgd=mgh
or `" " d=(h)/(mu)=(10^(-2))/(0.01)=1m`
