If a particle starts from A along the curved circular path shown in figure with tangential acceleration ‘a’. Then acceleration at B in magnitude is:
A.
aπ√1+π2
B.
a√π2−1
C.
a√1+π2
D.
2a√1+π2
Please scroll down to see the correct answer and solution guide.
Right Answer is: C
SOLUTION
V2B=V20+2a×πR2
V2B=aπR
Normal acceleration at B=V2BR=aπ
Net acceleration at B=√a2+a2π2=a√1+π2
