A spherical body moves with a uniform angular velocity (ω) around a circular path of radius r. 

Which one of the following statements is correct? 

(a) The body has no acceleration 

(b) The body has a radial acceleration ω2r directed toward centre of path 

(c) The body has a radial acceleration 2/5ω2r directed away from the centre of the path 

(d) The body has an acceleration ω2 tangential to its path

A person travelling on a straight line moves with a uniform velocity v_1 for some time and with uniform velocity v_2 for the next equal time.

(a) v = (v1 + v2)/2. Explanation:  Let t be the time related to each velocity. Total distance travelled =v1t+v2t. Total time taken=2t. Hence average velocity = v1t+v2t/2t  =(v1+v2)/2.

A person traveling on a straight line moves with a uniform velocity v_1 for a distance x and with a uniform velocity

(c)  2/v = 1/v1 + 1/v2. Explanation: Time taken during first phase =  x/v1 and during second phase =  x/v2.  Total distance =2x   Total time taken = (x/v1)+(x/v2) = x(1/v1 +1/v2)     Average velocity =Total distance/Total time taken ...

A circular disc A of radius r is made from an iron plate of thickness t and another circular disc B of radius 4r

(c) IA <IB   Explanation:  Let the density of iron plate be ρ.  Mass of first disc m = πr²tρ  M.I. = IA = ½mr² == ½πr²tρr² = ½πr4tρ  Mass of second disc = M =...
