just think about it.no resultant force is acting and the directiion of the charge from right to left frm positive to negative.so it will be anticlockwise

Tkp

cross multiplication
for X : in wire 1 : 3 m = 1.5 mm
in wire 2: 1 m = ? u get 0.5 mm
for Y : in wire 1: 1 m = 1 mm
3 m = ? u get 3mm
add them u get 3.5 mm
so i reckon 3.5 mm B is the answer

Force applied by person - mgsintheta - friction = 0
force applied by person = 200sin30 + 150
force applied by person = 250 N
work done = force x distance
250 x 1.5/sin30
750J

Can someone pls help with this qn?

Can someone pls help with this qn?View attachment 13008

da answr is C bcoz u c da uncertanity of da diamter will be twice bcoz its d^2.. so uncertanity will be 2d which will show da largest effect

if its 2d den the ans shud b B CUZ DIAMETER IS ON B NOT C

Would someone be kind enough to help me in June 10 variant 2 question 34. (I know this has been asked hundreds of times before but I can't find the sol. now).
Also, Nov 09 variant 2 question 18.

the ans is c.no resultant force is acting.as it is moving frm positive to negative so it will be anticlockwise

well , d positve charge is replled by a force awzy frm + terminal, da same 4 da - charge , whch will be replld by da same force, frm - terminal so equal magnitude, forces in opposte direction, zero resulatnt, if u conside da torque, da - charge attracts up while + charge down so anticlockwise.. hope u understand
