A particle experiences a constant acceleration for 20 sec after starting from rest. If it travels a distance \[{{S}_{1}}\] in the first 10 sec and a distance \[{{S}_{2}}\] in the next 10 sec, then [NCERT 1972; CPMT 1997; MP PMT 2002]

• A.             \[{{S}_{1}}={{S}_{2}}\]   
• B.             \[{{S}_{1}}={{S}_{2}}/3\]
• C.             \[{{S}_{1}}={{S}_{2}}/2\]
• D.             \[{{S}_{1}}={{S}_{2}}/4\]
