1.	A particle of 0.15 kg is attached on 21 and off the light extensible string length 2 metre the other end of the string attached to a fixed point the particle moves to the concept has drawn to a circle the magnitude of the acceleration of a particle is 7 metre per second the string make an angle theta with the vertical find the value of theta the nearest Whole number and the speed of the particle
Answer» Answer: At any time force ACTING on particle vary and hence acceleration (net) will have different direction at different times. TENSION also changes and its minimum at top point. Magnitude of acceleration also varies. Considering earth and particle as a system and no external force on system is acting, total MECHANICAL energy will be conserved.

Answer:

At any time force ACTING on particle vary and hence acceleration (net) will have different direction at different times. TENSION also changes and its minimum at top point. Magnitude of acceleration also varies.

Considering earth and particle as a system and no external force on system is acting, total MECHANICAL energy will be conserved.
