某同学用圆柱形容器制作了一个测量物体质量的装置，它的底部较重，可以竖直漂浮在水面，其总质量为0.21kg、底面积为3×10^－3m2。不放物体时，与水面所对应位置处的刻度线的标定值m₀为“0”，如图甲所示，求该装置所受的浮力F₁。若在该装置中放入一个体积为1.5×10^－5m3的物块，圆柱形容器的底部在水面下的深度h=0.11m，如图乙所示，求该装置受到的浮力F₂和此时与水面所对应位置处的刻度线的标定值m。

     It came as something of a surprise when Diana, Princess of Wales, made a trip to Angola in 1997,

to support the Red Cross campaign for a total ban on all anti-personnel landmines. Within hours of arriving in Angola, television screens around the world were filled with images of her comforting victims injured

in explosions caused by landmines. “I knew the statistics,” she said. “But putting a face to those figures

brought the reality home to me; like when I met Sandra, a 13- year-old girl who had lost her leg, and

people like her.”

     The Princess concluded with a simple message: “We must stop landmines”. And she used every

opportunity during her visit to repeat this message.

     But, back in London, her views were not shared by some members of the British government, which

refused to support a ban on these weapons. Angry politicians launched an attack on the Princess in the

press. They described her as “very ill-informed” and a “loose cannon”. (乱放炮的人)

     The Princess responded by brushing aside the criticisms: “This is a distraction (干扰) we do not need. All I’m trying to do is help.”

     Opposition parties, the media and the public immediately voiced their support for the Princess. To

make matters worse for the government, it soon emerged that the Princess’s trip had been approved by

the Foreign Office, and that she was in fact very well-informed about both the situation in Angola and the

British government’s policy regarding landmines. The result was a severe embarrassment for the

government.

     To try and limit the damage, the Foreign Secretary, Malcolm Rifkidnd, claimed that the Princess’s

views on landmines were not very different from government policy, and that it was “working towards" a

worldwide ban. The Defence Secretary, Michael Portillo, claimed the matter was “a misinterpretation or

misunderstanding.”

     For the Princess, the trip to this war-torn country was an excellent opportunity to use her popularity

to show the world how much destruction and suffering landmines can cause. She said that the experience

had also given her the chance to get closer to people and their problems.
